How it works

We record prices ourselves from official store data feeds and APIs, check each sale against the item's own price history, and only list what holds up.

Verdicts

• Real deal: at least 10% below the item's 90-day median price, with no sign the regular price was raised before the sale.
• Not a real deal: less than 10% below its 90-day median, or the listed regular price is more than 30% above the highest price we recorded, or the price was raised 10% or more in the 30 days before the sale.
• No verdict yet: fewer than 5 price checks over 14 days. These items are not shown at all. We do not guess.

A store's own "was" or list price is recorded but never trusted on its own. Verdicts describe the numbers we recorded, with the count of checks and the dates, not any store's intent.

What we never do

• Log in to a store, or copy store pages.
• Take paid placement. A commission never changes a verdict or a ranking.
• List car or auto deals.
• Take deal submissions.

Sold out?

When a hot item sells out at most stores, we show where it is still in stock, using each store's official availability data.
