How to Spot Fake Deals Online: A No-Nonsense Guide

Here is something that should make you slightly angry: a significant portion of the "deals" you see online are not deals at all. They are normal prices presented as discounts through a combination of inflated reference prices, manufactured urgency, and psychological tricks refined over decades of retail. This is not a conspiracy theory — it is well documented by consumer watchdogs including Which? and the Advertising Standards Authority, and it affects every major UK retailer to some degree.

We are not saying every sale is fake. Genuine discounts absolutely exist, and smart shoppers save real money during events like Black Friday and Prime Day. But if you cannot tell the difference between a real deal and a manufactured one, you are probably spending more than you realise. This guide will help you spot the difference.

The inflated RRP trick

This is the most common tactic and it is devastatingly effective. A product is listed at "was £100, now £60" — a 40 per cent discount that triggers an immediate sense of value. But was the product ever actually selling at £100? In many cases, the "was" price is the manufacturer's recommended retail price — a figure that exists primarily to make discounts look larger. Almost nobody pays RRP on consumer electronics, fashion, or home goods. The real market price might have been £65 to £70 for months, making the actual saving closer to five per cent.

The Competition and Markets Authority (CMA) has guidelines about reference pricing, but enforcement is patchy. Retailers can legally show a "was" price if the product was sold at that price for a meaningful period — but "meaningful period" is interpreted generously.

Phantom discounts

A phantom discount occurs when a retailer raises the price of a product shortly before a sale, then "discounts" it back to or near its original price. The product appears to be on sale, but the customer pays roughly what they would have paid anyway. Which? has documented this happening repeatedly during Black Friday, where some products were found to be cheaper in the months before the sale than during it.

This is particularly common with products that have fluctuating prices — electronics, fashion, and seasonal goods. A TV that sold for £350 in September might be quietly raised to £420 in October, then "reduced" to £360 for Black Friday. The deal label says you saved £60. In reality, you paid £10 more than you would have two months earlier.

Manufactured urgency

Countdown timers, "only 3 left in stock" warnings, and "X people are looking at this right now" notifications are all designed to reduce the time you spend evaluating a purchase. The logic is simple: the less time you think, the more likely you are to buy on impulse.

• Countdown timers — the deal may genuinely expire, but it often reappears later or is replaced by a nearly identical offer.
• Stock warnings — "only X left" may refer to that seller's stock, not the product's overall availability. The same product might be fully stocked at another retailer.
• Social proof notifications — "12 people bought this in the last hour" is often accurate but irrelevant. Other people buying something does not make it a good deal for you.
• Flash sales — time-limited sales create fear of missing out. The products in flash sales are not always the best value; they are often items with the highest margin or excess stock the retailer wants to clear.

The "compare at" price

Some retailers show a "compare at" price rather than a "was" price. This is subtly different — it suggests that other retailers are selling the same product at a higher price, implying you are getting a better deal here. The problem is that the "compare at" price might be from a single obscure retailer, or it might be outdated. It is technically accurate but practically misleading.

How to protect yourself

The good news is that spotting fake deals is not difficult once you know what to look for. Here are the practical steps we use on our own purchases.

Check the price history

Before buying anything marketed as a deal, check what the product has been selling for over the past few weeks or months. Price tracking tools exist for exactly this purpose. If the "sale" price is the same as or higher than the recent average price, the deal is not real. This single step will save you more money than any other advice in this article.

Compare across retailers

A deal is only a deal if it is the cheapest available option right now. A "50 per cent off" label means nothing if another retailer is selling the same product at a lower price without any sale. Using a comparison tool like WEM to check prices across multiple UK retailers takes seconds and immediately reveals whether a deal is genuinely competitive or just well presented.

Apply the 24-hour rule

Unless the product is something you were already planning to buy, wait 24 hours before purchasing. Urgency tactics are designed to bypass rational decision-making. If the deal is still available tomorrow and you still want the product, buy it. If it expires overnight, another similar deal will almost certainly appear within weeks.

Be sceptical of unfamiliar brands

During major sales events, unknown brands appear with enormous discounts on products you have never heard of. A "90 per cent off" wireless speaker from a brand with no track record is not a deal — it is a product that was never worth the inflated original price. Stick to brands with established reputations, or at least check independent reviews before purchasing.

We ran an experiment during Black Friday 2025: we tracked 30 popular products for the six weeks before and during the sale. Only 18 of the 30 were genuinely cheaper on Black Friday than at any point in the prior six weeks. The other 12 were either the same price or actually more expensive. Price comparison through WEM was the fastest way to verify each one.

Why this matters more than ever in 2026

Online retail has become more sophisticated, not less. Dynamic pricing — where the price you see changes based on demand, your browsing history, or even the time of day — is increasingly common. Sale events have multiplied: Prime Day, Black Friday, Cyber Monday, January sales, spring sales, mid-season sales, and countless retailer-specific promotions mean there is always a "deal" available somewhere. The sheer volume makes it harder to evaluate each one individually.

The most powerful tool in your arsenal is not a specific website or browser extension — it is the habit of pausing for ten seconds before buying anything on sale and asking: "Is this actually cheaper than normal, and do I actually need it?" Combine that instinct with a quick price comparison, and you will avoid the vast majority of fake deals without any extra effort.
