A huge percentage-off label, a countdown clock and a polished-looking product page can make an offer feel urgent. None of those things proves it is a genuine bargain.There are two different risks to watch for: an offer that is real but not especially good value, and an outright scam where the supposed retailer takes payment or personal information without delivering what was promised. This guide explains how to check both before clicking Buy.
1. Look beyond the crossed-out price
A product advertised at '£49, was £129' may appear to offer a spectacular saving. But the important question is whether £129 was a genuine, established selling price. Some products spend more time on promotion than at their suggested full price.Check the exact model number across several reputable retailers. Look at comparable prices, delivery charges, warranty conditions and, where available, independent price histories. Avoid comparing different storage capacities, generations or bundles as if they were the same item.The UK's Advertising Standards Authority advises that savings claims should use meaningful reference prices. An RRP on its own is not proof of what shoppers usually pay.2. Check the website address carefully
Scammers can copy a familiar shop's logo, colours and product photographs. Look for unexpected extra words, unusual spellings or strange domain endings in the address bar. A padlock or HTTPS connection does not prove that a shop is legitimate; it simply describes the connection's security.If an offer arrives via a message or social media advert, consider opening a new browser tab and navigating to the retailer's known official website yourself rather than following the supplied link.3. Research the seller, not just the product
Look for clear contact information, a company identity, delivery information and a returns policy. Check reviews on independent services and compare both positive and negative experiences. Be cautious when every review is very recent, vague or unusually enthusiastic.For marketplaces, distinguish a sale by the platform from one by an independent marketplace trader or private individual. Check who will actually supply the product and handle a problem.4. Be wary of pressure tactics
A sale ending tonight may be genuine, but false scarcity can push shoppers into skipping checks. Treat permanent countdown timers, unexplained 'only one left' messages and extreme discounts on hard-to-find items as prompts to investigate, not reasons to rush.An offer that cannot withstand five minutes of checking is rarely worth risking your money or account details.5. Understand how you are being asked to pay
The National Cyber Security Centre recommends paying by credit card when possible and warns against paying unfamiliar online sellers by direct bank transfer. Debit card purchases may qualify for chargeback under card-scheme rules; some credit card purchases may have additional statutory protection. Payment-platform protections depend on their conditions.Be especially cautious when a seller asks you to leave a marketplace's payment system, buy gift cards or send money to a personal account. Never share one-time passcodes sent by your bank with a retailer or courier.6. Check the full price including delivery
A cheap headline price can become uncompetitive when delivery, minimum spend, subscriptions or compulsory extras are added. If a discount requires a voucher, test it at checkout before assuming it applies. Check whether it excludes clearance items, certain brands or particular product variants.For subscriptions, calculate the price over the entire term rather than judging the first month alone.7. Verify that the item and seller are what you expect
Before paying, check the exact model code, colour, size, region, and whether the item is new, refurbished, used or sold without accessories. Some marketplace listings use the main product photograph but offer a cheaper accessory or replacement part as the selected variant.Save a screenshot or PDF of the full listing, stated condition, total price, delivery estimate and returns terms. That record can help resolve disputes.8. Remember that discounts do not remove consumer rights
UK consumers buying from traders generally retain their statutory rights when an item is faulty, not as described or unfit for purpose—even if it was in a sale. For most online trader purchases, there is also a separate 14-day cancellation period for changing your mind, with exceptions. A private seller transaction is different, so identify the seller before buying.Red flags worth investigating
- A well-known brand at an implausibly low price from an unfamiliar site
- A recently created or strangely spelled website address
- Only bank transfer, cryptocurrency or gift-card payment accepted
- No credible company details or returns instructions
- Unrealistic review scores or recycled product photographs
- An urgent message asking you to click a delivery-payment link
- A claimed previous price you cannot corroborate
- A checkout total far higher than the headline offer
