That “was €199”? We checked.

The chart, not a claim

Every verdict comes with the dated price history we recorded ourselves. The 30-day low, the claimed price and today's price, side by side.

Whole shops, in one number

/shop tells you what share of a catalogue is permanently “reduced”. Some shops we watch sit at 98 %. Others at 0 %. Now you know which is which.

Drops that actually happened

/deals lists the biggest price cuts we observed with our own eyes: old price, new price, date. Never a shop's struck-through number.

How it works

Paste a link - or right-click any message and choose Check this deal. Works in any server, including ones where the bot is not installed.
We look up the history - 4227 shops and about 21,590,000 offers, checked around the clock since September 2026, growing every week.
You get a verdict - Real discount, Smaller than claimed, Not a discount or Too early to tell, with the chart to back it up. Share the picture.

What makes it trustworthy

Checked daily against the shops themselves: on 2026-11-06, 3 of 4 sampled prices matched exactly.

It only says what it saw. Not enough history means “too early to tell” - never a guess dressed up as a verdict.
Every verdict carries its dates. You can check our work.
It reads only what shops publish for machines, honours robots.txt and never works around a block. Shop owners can opt out with one line.
It has nothing to sell you. No affiliate links, no ads, no sponsored deals. The verdict cannot be bought.
It judges prices, not shops. We report what we observed. What it means is for you to decide.

Then keep watching

/track a product - or a single size - and hear about it the moment it drops or comes back in stock. /watch a whole shop for new products, restocks and drops. /feed posts the day's real drops into your channel every morning.
