How we check prices

Stores often show a "was" price that the product rarely sold for. That makes a normal price look like a sale. We don't use those numbers to decide what's a deal.

1. We record the price every day

Once a day, we save each product's price at the store, along with whether it's in stock and the store's "was" price, if any.

2. We compare today's price with its usual price

A product's usual price is the median of every price we recorded over the last 90 days. Half the time it was cheaper, half the time it cost more. Our headline number is how far today's price is below that: "% below its usual price." The store's own "% off" claim is shown smaller, next to it, so you can compare.

3. We label the deal

Labels come only from the price history we recorded, never from the store's "was" price.

Lowest price ever

Today's price is at or below the lowest price we've ever recorded, and we've tracked it for at least 30 days.

Lowest in 90 days

Today's price is the lowest we've seen in the last 90 days.

Below its usual price

Today's price is at least 10% below its 90-day median.

No real drop

Today's price is at or above its usual price. These products never appear in our rankings or store shelves.

Store's "was" price looks inflated

A separate warning. We show it when the store's "was" price is higher than any price we recorded in the last 90 days.

How we rank

Rankings sort by % below the usual price. When two deals tie, the one that saves you more dollars comes first.
