Is it a real discount? How to check a deal in two minutes

“Was £199, now £99” only means something if people were actually paying £199. Here’s how to check a deal quickly, and what the rules say a shop is allowed to claim.

The short version

Look up the price history, check two other shops for the same model number, and add on delivery. If it’s still cheaper than usual, it’s a real deal.

The five checks

  1. Price history. This is the single best check. If today’s price is at or near the lowest on the chart, it’s a good deal. If the line was lower last month, wait.
  2. The “was” price. Ask when it was last that price, and for how long. A “was” price from a short burst months ago, or a “save £100 off RRP” on something nobody sells at RRP, is a red flag.
  3. The exact model number. Search the full model code at two other shops. Sale-only versions of TVs, laptops and appliances sometimes have different specs, which makes them hard to compare.
  4. The total cost. Add delivery, installation, removal of an old appliance, and any “optional” extras that are ticked for you. A discount that disappears at checkout isn’t a discount.
  5. The pressure. Countdown timers, “3 people are looking at this” and “last few left” are there to stop you doing checks 1 to 4. A good deal survives five minutes of thinking.

What the rules say

UK law bans misleading prices, and the official guidance for shops, the Pricing Practices Guide, sets out what makes a “was” price fair:

The old “28-day rule” you may have heard of was dropped in 2016. Shops now have to judge whether a comparison is fair, which is why some still push their luck.

Enforcement got tougher in April 2025. Under the Digital Markets, Competition and Consumers Act, the Competition and Markets Authority can now fine businesses directly, up to 10% of their global turnover. Its first fine, in April 2026, was £4.2 million for a booking fee that only appeared at checkout. It is also investigating misleading time-limited offers.

Common questions

Is RRP the same as a “was” price?

No. RRP is the price the maker recommends. If nobody actually sells at RRP, a “save £50 on RRP” is a much weaker claim than a genuine price drop.

Are price trackers accurate?

They’re a guide, not a guarantee. They check prices at intervals, so they can miss very short flash sales. Use them to see the pattern, then check the live price on the shop’s site.
