Latest / The Pricing Marketing Podcast with Fexingo: Price Anchoring, Bundling, and Conversion Pricing / How a 10 Percent Coupon Anchors You to Pay Full Price
Transcript
- Lucas: So, you get a coupon in your email — ten percent off your next purchase. Feels like a gift, right? Luna: I mean, yeah. I'd be more likely to buy something. Lucas: That's the intuitive answer. But there's a really interesting counterintuitive finding: a ten-percent-off coupon can actually anchor you to pay full price. And in some tests, people who got the coupon ended up spending more — not less — than people who got no discount at all. Luna: Wait — how does getting a discount make you spend more? That sounds backwards. Lucas: It's a variation on the decoy effect we've talked about before, but in reverse. The coupon creates a reference point — a 'discounted' price. Suddenly the full price doesn't look like a price anymore; it looks like a premium you'd pay to not use the coupon. And for some shoppers, that premium feels like a signal of quality. Luna: So the coupon becomes an anchor that makes the regular price seem more legitimate? Lucas: Exactly. There was an A/B test run by a mid-tier clothing retailer — let's call them 'Urban Threads' — where they split their email list. One group got a standard ten-percent-off coupon. The control group got no coupon at all. The coupon group had a higher conversion rate, but — here's the kicker — their average order value was actually higher than the control group. They bought more full-price items. Luna: That's wild. So the ten-percent-off coupon somehow justified buying the full-price jeans? Lucas: That's exactly what happened. The coupon gave them a psychological license to spend. They felt like they were getting a deal on the overall basket, so they stopped hunting for sale items and just bought what they wanted at full price. The control group — no coupon — was more price-sensitive, more likely to buy only discounted clearance items. Luna: So the coupon actually shifted their mindset from bargain-hunting to quality-seeking? Lucas: Right. And this works best when the discount is modest — ten percent, maybe fifteen. If it's thirty percent off, the anchor flips. Then the full price looks like a rip-off, and people wait for the big sale. But a small discount? It just reaffirms that the regular price is fair. Luna: That explains why premium brands almost never do percentage-off coupons. You never see Apple sending out 'ten percent off AirPods' emails. Lucas: Exactly. Apple, Lululemon, Hermès — they rarely use percentage-off discounts because they don't want to create that anchor. Once you've told a customer the product is 'worth' ten percent less, you've subtly undermined the premium perception. But a flat-dollar discount — like fifty dollars off a thousand-dollar laptop — doesn't trigger the same contrast effect. Luna: Because fifty dollars feels like a rounding error, not a percentage game. It doesn't reset the anchor. Lucas: That's the insight. A percentage discount is a relative anchor — it tells the brain 'this item is usually cheaper by X percent.' A flat dollar amount is an absolute anchor — 'here's a small token.' So the psychology is completely different. The Urban Threads test actually ran a second variant with a flat five-dollar-off coupon. That group's average order value was lower than the ten-percent group. The flat discount didn't create the same permission to spend effect. Luna: So the structure of the discount — not just the amount — changes behavior. That's the kind of nuance most marketers miss. Lucas: And it gets even more interesting when you look at how the coupon is framed. 'Ten percent off your entire purchase' versus 'Ten percent off one item.' The 'entire purchase' frame actually increased basket size more, because it encouraged adding higher-priced full-price items to 'maximize' the discount. Luna: Right — you think, 'I'm getting ten percent off everything, so I might as well buy the expensive coat I was eyeing.' The discount becomes a justification for a bigger purchase. Lucas: And that's exactly what the retailer wants. They're not losing margin on every item — because many of those items wouldn't have been discounted otherwise. The coupon effectively increases the share of full-price sales in the basket. Luna: So if you're a marketer, the takeaway is: use small percentage-off coupons strategically to anchor customers to full price, not to drive them to clearance. Lucas: Exactly. And be careful with the discount size. Too small and it's irrelevant; too big and it trains customers to wait. The sweet spot seems to be between eight and twelve percent for most consumer goods. But you have to test it for your specific category. Luna: Honestly, if today's episode sparked something you've actually used in your own pricing, that's what keeps this show ad-free.

Now, let's talk about one more twist — the expiration date on that coupon. Luna: You mean how a short expiration can amplify the anchoring effect? Lucas: Exactly. When a coupon expires in 24 hours, it creates urgency. But it also makes the anchor more salient. The brain thinks: 'I have to decide now — and this ten-percent-off makes the full price feel like the normal, acceptable price.' So you're more likely to buy at full price right away rather than wait for a better deal. Luna: So the time pressure reinforces the anchor. That's clever. Lucas: But it's a double-edged sword. If you do it too often, customers learn to ignore your emails. The key is to use it sparingly — maybe once a quarter — so the anchor stays fresh. Luna: So the ten-percent coupon isn't really a discount tool. It's a behavioral nudge to buy full price. Lucas: Exactly. And that's why it's such a powerful tool in the pricing marketer's toolkit. It's not about giving away margin — it's about framing the entire purchase experience.
