Key takeaways
- A percentage off is only as honest as the "was" price it is measured against. Always ask: was it ever actually sold at that price?
- Check price history, compare other retailers, and check who is selling and shipping before you decide.
- Urgency (countdown timers, "only 3 left") is a nudge, not evidence of a good price.
- Your consumer rights do not depend on whether something was on offer.
In this guide
Deals are everywhere, and so are misleading ones. The good news is that a few quick checks will protect you from most of them. This guide is a checklist you can use on any listing, on any day of the year.
Start with the "was" price
A discount is a comparison: this price versus a reference price. The reference is often the manufacturer's recommended retail price (RRP) or an earlier selling price. The problem is that the RRP may be higher than the product has ever really sold for, so a big "percentage off" label can describe a perfectly normal price.
UK consumer protection law prohibits misleading price claims, and the rules on this were updated in 2025, but that does not stop you from checking for yourself.
A five-minute checklist
- Look at the price history. Price-tracking websites and browser tools, such as Keepa or CamelCamelCamel, show how a price has moved over months. If the item has sat at roughly the same price for ages, the "deal" is the normal price.
- Compare other retailers. Search the exact model number. If three shops sell it for the same, the saving is not special.
- Check the seller and the shipping. Is it sold and dispatched by Amazon, or by a third-party seller? Does the price include delivery? A low price from an unknown seller with slow dispatch is not the same deal.
- Check the exact version. The colour, size, storage or pack that is discounted might not be the one you want. Prices often differ between variants.
- Read the lower-star reviews. They tell you about faults and misleading descriptions. Be wary of a product with a flood of very short, similar five-star reviews.
Pressure tactics to ignore
- Countdown timers and "only 2 left". They are designed to make you decide quickly. Neither proves the price is good.
- Huge percentages. A large percentage on an unfamiliar brand is not the same as a large saving on a trusted product.
- "Limited time" without an end date. If the end date is not stated clearly, the deadline may not be real.
- Coupons you must clip. They can be real savings, but check the final price at checkout, not the headline.
Watch out for subscription traps
Some listings offer a lower price if you tick a subscription or a recurring delivery box. That can be a genuine discount, but make sure you know how to cancel and what the price becomes afterwards.
What counts as a good deal
A good deal is a price that is low compared with its own history and with other shops, on the exact product you want, from a seller you trust, with a returns policy you are comfortable with. Everything else is decoration.
Know your rights
Your rights under the Consumer Rights Act 2015 apply whether or not an item was on offer: goods must be as described, of satisfactory quality and fit for purpose. If you pay by credit card, Section 75 of the Consumer Credit Act can give extra protection on purchases between £100 and £30,000.
How BigDropUK handles prices
We link directly to the exact Amazon UK listing. We only show a price when we hold a current one, and otherwise say so and send you to Amazon to check the live price. Prices change quickly, so the figure on Amazon at checkout is the one that counts.
A worked example
Imagine you are looking at a pair of headphones with a large reduction badge.
- The badge: it compares against a "was" price. You open a price-history chart and see that the item has hovered around the same price for months, and the "was" price appeared once, briefly. The reduction is mostly decoration.
- The comparison: you search the exact model number elsewhere and find a similar price at two other shops. So the Amazon price is normal, not special.
- The seller: the listing is sold and dispatched by a third-party seller you have never heard of, with delivery taking longer than you would like.
- The verdict: it is not a bad price, but it is not a deal. You can buy it if you need it, or wait for a real drop.
Now imagine the history chart shows a clear dip well below the usual range, the seller is Amazon itself, and the returns window is generous. That is a deal worth acting on.
Red flags at a glance
- A discount percentage that is large but the "was" price is oddly high.
- A very low price from a seller with few or no reviews.
- A price that only applies to one colour or size you do not want.
- Reviews that are all short, similar and posted in the same few days.
- A "deal" that disappears when you add it to the basket or change the quantity.
- Pressure wording with no clear end date.
Good habits that save money all year
- Keep a short wish list with the price you would be happy to pay.
- Use price alerts instead of checking every day.
- Wait 24 hours before buying anything that is not on your list.
- Record your order confirmations in case you need a refund.

Frequently asked questions
What is a "was" price?
It is the reference price a discount is measured against. It may be the manufacturer's recommended price or a previous selling price. Neither guarantees the product has been regularly sold at that level.
Are price history tools reliable?
They are a useful guide because they show how a price has moved, but they depend on how often prices are recorded, so use them as one signal rather than proof.
Is a Lightning Deal always a good price?
No. Some are genuinely good, some are only small reductions. Judge it the same way as any other price: compare it with history and with other retailers.
Can I still return something I bought on offer?
Yes. Your statutory rights, such as the right to a refund for faulty or misdescribed goods, do not depend on the item having been discounted.
