How to tell if a sale price is actually a discount
The crossed-out number is doing more work than the one you pay. Here is what it actually means.
Almost every discount you see is presented the same way: a higher number, struck through, sitting next to a lower one. That layout is not decoration. It is there because of how people judge value — we are poor at knowing what a thing should cost in absolute terms, and very good at comparing two numbers placed side by side. Give someone a reference point and they will judge the price against it rather than against the market.
Which means the crossed-out number is the most important part of the offer, and the part least often checked.
What a "was" price is supposed to mean
In the UK, a reference price is not meant to be a decorative higher number. The principle behind the rules is that a "was" price should reflect a genuine previous selling price — a price the retailer actually sold that product at, for a meaningful period, reasonably recently. A price that was live for a weekend in a single shop, or that nobody ever paid, is not a fair comparison, and presenting it as one can be a misleading practice.
The same logic applies to the other reference prices you see: "RRP", "list price", "elsewhere". Each is a claim about a comparison, and each is only useful if the comparison is real.
The four checks
1. Ask when the "was" price was last the actual price
This is the single most useful question, and price history tools exist precisely because retailers do not answer it on the page. A product that has sat at the "sale" price for most of the year is not on sale. It has a price, and a decorative higher number above it.
2. Check the price at a different retailer, not a different page of the same one
A discount is a comparison against the market, not against the shop's own previous number. A retailer can only tell you about its own pricing. If three other shops sell it lower without calling it a sale, the sale is not a saving.
3. Add the costs that come after the price
Delivery, returns postage, minimum spend to unlock free shipping, an installation fee, a required accessory sold separately. The cheaper headline price frequently loses once these land. Compare what leaves your account, not what appears in the largest font.
4. Notice whether the discount arrived with a deadline
A genuine price cut does not usually need a countdown timer attached. Urgency is added when the seller wants the decision made before you compare — which tells you something about how the price would fare if you did.
The sales that are usually real
Not every discount is theatre. Reductions tend to be genuine when the retailer has a reason to want the stock gone rather than a reason to want you to hurry:
- End-of-line and discontinued stock — the model is being replaced and the shelf space is needed.
- Seasonal clearance — garden furniture in autumn, coats in spring. The retailer is paying to store something nobody is buying.
- Ex-display and open-box — a real reduction for a real, disclosed flaw.
- Superseded technology — last year's model when this year's lands. Often the best value in the shop, because the change between generations is usually smaller than the price gap.
What these have in common is that the discount exists to solve the seller's problem. That is the kind of discount that tends to be worth taking.
The one habit that replaces all four checks
Checking properly takes a few minutes per purchase, which is exactly why almost nobody does it and exactly why the tactics keep working. The practical fix is not more discipline. It is doing the comparison at the moment you are already on the page, before the decision has been made rather than after.
