50% off or fake? How to tell a real discount from the real price

Every shopping season — Yalda, Black Friday, the year-end sales — the same question forms in an Iranian shopper's mind: is this discount real or fake? When the screen says "50% off" with a big strikethrough number above the new price, you feel you're about to miss a golden deal. But in a market where prices rise and fall with currency swings and inflation, that crossed-out number is often invented. Spotting a fake discount means learning to check the real price of the same product at several other sellers instead of trusting the seller's claim.

The classic trick: raise the price first, then "discount" it

The most common fake-discount move works like this: a few days before the sale, the seller artificially inflates the base price, then strikes through that inflated figure as the "original price" and puts the current price underneath. The result is a dramatic discount on screen, while the final price may actually be higher than the normal price two weeks ago. A strikethrough on the page guarantees nothing; that "was" price is just a number the seller typed, not a reality that ever existed in the market.

• The base price is raised days before the sale to make the discount percentage look bigger.
• The crossed-out "original price" was often never the real selling price.
• The "50% off" label sits on an arbitrary number, not the market median.
• Countdowns and "today only" create psychological pressure to buy before you check.

What does the real price actually mean?

The real price of a product is not a number one seller claims; the real price is the market median — the right-now price of that same product across several different sellers. When you line up five or ten sellers, you get a range of prices, and the number in the middle of that range tells you what the product is genuinely worth. A discount is real when the final price is below this median, not below a figure the seller wrote at the top of the page.

Three steps to test any discount

• Check the live price of the same product at other sellers — not a cached number, but the price sitting on the seller's own site right now.
• Look at several sources at once; compare Torob, Digikala, and Emalls together so no single shop owns the whole story.
• Watch the price pattern: if the crossed-out "was" price matches today's market median, the discount is probably real; if it's far above, you're looking at an inflated number.

The wrong-model, wrong-pack trap

One of the sneakiest forms of fake discount is swapping the model or pack. A dramatic discount sits on a smaller version, a lower capacity, or a single-unit pack that, at a glance, looks exactly like the more expensive product. You think you bought 1kg of sugar on sale, when the price was on the 50g pack. For a fair comparison you have to be sure you're measuring exactly the same product, in the same model and pack — not something that merely resembles it.

Did I overpay? How to find out

Sometimes the worry runs the other way: there's no sale at all, but after buying you tell yourself "I think I overpaid." The fix is simple: compare what you paid against today's real range for the same product. If your amount is inside the range or below the market median, it was a fair buy; if it sits above the range, you overpaid — and next time you know where to look. This is the same logic behind finding the cheapest price and doing a proper price comparison: it tests what you paid against market reality, not against one seller's claim.

How Price Finder exposes a fake discount

To spot a fake discount, Price Finder does exactly what is tedious to do by hand: it searches the product name in your own words across Torob, Digikala, Emalls, and Google at once, and for aggregators it opens the seller's own site and reads the live, right-now price instead of the cached "from N shops" figure. An AI relevance pass then keeps only the genuine product and tags each result exact, variant, or related, so you never accidentally compare a smaller model or pack. Outlier and unit-error prices are dropped, the freshness of each price is flagged (up-to-date or old, with the source date), and within seconds the real market median is in front of you. Now just measure the discounted price against that median: if it's still above, the "50% off" was fake — and before your Yalda or Black Friday purchase, you got the real price first.
