Earned value
Something customers work towards: points, stamps, credit towards a future purchase, a free item after reaching a threshold, a bonus for completing a goal. Progress itself is part of the reward.
Rewards, not discounts
Rewarding loyalty is not the same as discounting.
If “loyalty programme” sounds to you like margin quietly given away on sales you were winning anyway — good. That instinct is right, and it’s exactly the problem well-designed rewards avoid. This page makes the case, with the research to back it up.
The hidden cost
Blanket discounts pay the wrong people.
Suppose 100 customers see a 20% discount. Thirty of them were already going to buy today. Another eight decide to buy because of the promotion.
The promotion generated eight incremental customers — but the business funded a discount across 38 transactions. Thirty full-price sales just became discounted ones, and the deal caused none of them.
Researchers describe the same leak more formally. A large randomised field experiment with a hotel loyalty programme separated customers whose behaviour genuinely changed because of an incentive from customers who would have met the purchase requirement anyway. Only the first group creates incremental value; the second still collects the reward.3
For an owner the principle is much simpler:
Don’t pay for behaviour you were already going to get.
A discount reduces a price. A reward nudges demand, reinforces loyalty, seeds an idea, builds a habit, or challenges a mindset.
There is an important difference between “everything is 15% off today” and “do this and earn something valuable”. The first cheapens transactions whether the promotion caused them or not. The second gives a customer a reason to change the way they shop now and in the future.
“Everything is 15% off today”
Cuts the price for everyone — including the customers who would have paid full price. Trains people to respond to the deal, not the business. When the discount stops, so does the reason to come.
“Do this and earn something valuable”
An earned free coffee. Bonus points past a spend threshold. An upgrade for a regular. Early access to something new. Each one creates progress — and a customer six stamps into a ten-stamp card is no longer just comparing today’s prices.
That distinction shows up in the research. A meta-analysis covering four decades of loyalty programmes — 110 studies and 429 measured effects — found strong evidence that programmes change behavioural loyalty: how often customers buy, how much they spend and whether they keep coming back. But reward design mattered. Programmes built on plain discounts showed weaker loyalty effects, while savings-based rewards — accumulated points, “buy nine, get one free” — showed stronger effects.1
That is why the humble stamp card still works. A customer approaching a reward has something to lose by switching away. The objective isn’t to discount more — it is to spend promotional budget where it has the best chance of changing behaviour.
There’s a second cost to frequent discounting that never shows up on the promotion’s own report: it trains customers to wait. Once people learn the sale comes round regularly, they time their purchases to it — and full-price weeks quietly empty into discounted ones. The habit being built is checking for the deal, not visiting the business. Earned rewards train the opposite rhythm. Progress on a card, a reward waiting on the next visit, a milestone approaching, news worth checking in on: each visit makes the next one more likely. That is the habit worth building — choosing you by default, not waiting for money off.
A reward doesn’t need a percentage sign or a $ sign
A good reward answers one question: what would this customer value enough to take the next step? Sometimes that’s financial. Often it doesn’t need to be.
Better treatment
Value that never hits the till as a price cut: a complimentary upgrade, priority booking or collection, extra flexibility, an enhanced service, a small extra with an existing purchase.
Access & exclusivity
Things ordinary customers can’t simply buy: early access, member-only products, previews, limited releases, priority tickets, invitations and experiences.
The 40-year meta-analysis distinguishes financial rewards from psychological benefits such as exclusivity and preferential treatment — and found exclusive rewards associated with stronger loyalty effects, while rewards unrelated to the business’s core offering performed less well.1 A restaurant might offer priority access to a special menu; a salon an upgrade; a bakery a limited product; a venue priority booking.
There’s a sharper way to put that finding to work. Every business has something it tries to do better than the rest — quality, customer service, a deeper range, faster turnaround, better taste, a more ethical way of working. Use rewards to steer customers towards exactly that. If your edge is quality, reward a taste of the premium line. If it’s service, reward priority treatment. If it’s range, reward discovery of a category they haven’t tried. If it's ethics - make sure they get that message. A discount says “we’re cheaper today”; a reward built on your strength says “here’s why you come to us” — and every redemption reinforces the reason to keep coming back.
Start with something customers already value about your business — then make more of it available as a reward.
Measure what matters
Judge rewards on incrementality, not redemption.
A promotion with an impressive redemption rate can still be a poor promotion. Imagine £5 off a product your regulars buy every week. Redemption would be huge. Incremental revenue could be close to zero — the reward has simply replaced full-price sales with discounted ones. Researchers call this substitution.
A 60-week study of a grocery loyalty programme modelled this directly, comparing accumulated points rewards with individually targeted coupons. Its conclusion was clear: targeted offers became substantially more profitable when they were aimed at purchases that would not otherwise have happened — with improved targeting having the potential to lift coupon profitability by more than 200% at the retailer studied.2 The same discount can have very different economics depending on who receives it and what behaviour it changes.
The same study found the two instruments do different jobs — and work best together. A points redemption had the larger effect per redemption on whether a customer shopped again; targeted offers were used far more often and generated more incremental spend overall.2 Persistent rewards build momentum. Directed rewards intervene where a particular behaviour is worth encouraging. The objective isn’t to replace the stamp card — it is to make loyalty smarter around it.
Different customers deserve different investment
A randomised experiment across 23,583 hotel loyalty customers tested different reward sizes and qualifying hurdles. Which customers responded changed with the design — and models that ignored those differences recommended incentives up to 50% too large and predicted profits up to 100% too high.3 You don’t need econometrics to use the lesson. Start from the behaviour a customer already shows, and ask what useful next behaviour might realistically change.
The occasional customer
Likes you, visits rarely. Progress towards an earned reward or a next-visit bonus gives them a reason to come back sooner. The opportunity is frequency or to chose you more often.
The regular
Already visits often — 15% off everything just discounts revenue you were winning. Offer status, upgrades, priority or exclusive access instead. A surprise birthday reward may make them feel more appreciated. The opportunity is retention and share of wallet.
The customer close to a goal
Eight stamps of ten. Make the progress visible and the finish line clear. The opportunity is completion — and a reminder may be all it takes to prompt another visit.
The one-category customer
Buys coffee but never lunch; treatments but never products. A well-chosen bonus, taster or upgrade lowers the risk of trying something new. The opportunity is discovery.
The customer drifting away
Stopped visiting — and may need a stronger reason to return than someone who was coming anyway. This is where a generous, targeted incentive earns its keep. The opportunity is reactivation.
If aiming rewards at people who rarely visit sounds optimistic, the evidence says otherwise. A two-year study of a convenience store loyalty programme found that heavy buyers claimed the most rewards but didn’t change their behaviour — while light and moderate buyers gradually bought more and became more loyal, with light buyers also branching into parts of the business they hadn’t used before.4 The customers with the most room to grow are the ones a blanket discount ignores — and the ones a well-aimed reward moves most.
Start with the behaviour, then choose the reward
Don’t begin campaign design with “should we offer £5 or 10%?”. Begin with “what are we trying to make happen?” — then select the reward that fits.
| Business objective | Behaviour to encourage | Possible reward |
|---|---|---|
| Win new customers | Join the programme — and come back again | 10% off today when you join, then £5 off a £30+ spend within two weeks — a welcome designed to start a habit, not a one-off deal |
| Increase visit frequency | Come back sooner | Double stamps this week, bonus points on the next visit, a reward that unlocks on the visit after this one |
| Increase basket value | Spend above a useful threshold | “Spend £25, earn a free coffee voucher” — a free item or bonus points that only trigger above your usual average basket size |
| Encourage trial | Buy from another category | A taster or sample with a regular order, bonus points on the untried category, an upgrade on a first booking of a new service |
| Strengthen retention | Keep choosing the business | A milestone reward at ten visits, earned status with priority booking, member-only access to a special menu or line |
| Reactivate a customer | Return after a period away | A time-limited “we miss you” voucher — valid this week only, sent only to customers who haven’t visited in months |
| Shift demand | Visit at a quieter time | A voucher valid 8–10am on weekdays, double stamps on quiet afternoons — peak trade stays at full price |
| Stay front of mind | Think of you first next time | News of a new line, a seasonal menu or an event — often no reward needed at all |
| Protect margin | Create value without cutting price | Early access to a release, priority collection, a complimentary upgrade — value that never arrives as a price cut |
Acquisition is the exception that proves the rule about discounting. A joining offer is one of the few discounts that is almost incremental by definition — the customer wasn’t yours yet. The design still matters: pair the day-one saving with a second, time-limited reward (“£5 off when you spend over £30 in the next two weeks”) so the offer buys a second visit and the start of a habit, not just one transaction. And aim it well — through LoyLocal’s Offers Near You search and nearby promotions, a welcome offer can reach people already out shopping locally, when a first visit is genuinely plausible rather than hypothetical.
Notice that one of the most valuable rows costs nothing at all. Loyalty isn’t only built at the till — it’s built between visits. A new collection landing, a seasonal menu, an event next week: plain news keeps the business front of mind and gives customers a reason to return at zero margin cost. The cheapest incentive is often just being remembered — save the rewards for the behaviour news alone won’t move.
Every reward has two sides: what the customer must do, and what they get for doing it. In “spend £25 → 250 bonus points”, the hurdle and the reward are separate decisions — the hurdle sets who qualifies, the reward sets how motivated they are. The hotel experiment varied both, and found substantial differences in response across customer groups and designs.3 The discipline that follows: set a hurdle that represents valuable incremental behaviour for your business, then offer enough reward to the customer to make it attractive. Not more.
Three questions before any promotion
Every reward has a cost. The objective isn’t to eliminate it — it is to make sure the behaviour generated is worth more. Incremental value created, minus reward cost, minus margin lost to substitution: that’s the value of a promotion.
Would they have bought anyway?
If yes, think twice before discounting the transaction. Recognition, status or access may create loyalty without giving away the sale you already had.
Will the reward change something useful?
Another visit. A larger basket. A new category tried. A return after months away. If a promotion won’t change behaviour, it will only redistribute margin.
Is the change be worth the incentive?
More reward isn’t automatically better — the research found oversized incentives are a common and expensive mistake.3 Aim for the smallest incentive that works.
The principle
The smallest effective incentive
Reward the next visit. Reward the bigger basket. Reward discovery. Reward the customers worth winning back. Reward behaviour worth rewarding — not every transaction. The goal is the smallest effective incentive, not the largest discount customers will accept.
Built to reward behaviour, not to cut prices
LoyLocal is designed around exactly this model: a persistent programme that turns visits into a habit — progress, earned value and a reason to come back — with directed rewards layered around the commercial behaviours that matter, and the numbers to show whether each one is paying its way.
Points & stamps that build progress
Flexible earning and redemption rules give customers something to work towards — the savings-based mechanism the research links to stronger loyalty.
Rewards tied to qualifying behaviour
Basket campaigns trigger at the till when a customer crosses a spend threshold or buys qualifying products — the reward only exists where the behaviour does.
Audiences, not blanket offers
Reach people by visit pattern, spend or location: a win-back voucher for drifted regulars, a quiet-morning offer, a nearby promotion — without discounting peak trade.
Rewards beyond money off
Member-only offers, early access to news and new lines, upgrades and partner vouchers at complementary businesses — value that doesn’t have to arrive as a price cut.
Timing & milestones
Time-windowed offers shift demand into quiet periods; milestone and next-visit rewards keep progress visible and give the customer a finish line.
Analytics that answer the real question
Not just “how many people used the offer?” but what it cost as a share of spend, which checkouts it influenced and whether vouchers got redeemed — so you keep the campaigns that lift spend and retire the ones that only discount it.

The commercially useful conclusion is the broader one: reward design, targeting, qualifying behaviour and substitution all materially affect whether a promotion creates incremental value or simply gives away margin.
