How we pick deals

Every deal here is a drop in the price anyone can get on Amazon, judged against that product's own price history.

Where the deals come from

Hourly drops are checked at the top of every hour: products whose price fell at least 20% below their 90-day average and that rank in the top 20,000 best sellers of their category (Clothing, Shoes & Jewelry: 25% and the top 5,000, since so many sizes and colors go on sale). We list a product again within 24 hours only if it gets at least 3% cheaper.

Ongoing deals come from each category's best sellers rated 4.0+ stars with 50+ reviews that are at least 10% below their 90-day average. They stay listed while they pass every check below.

How we measure a discount

We compare today's price with the product's own price history, not with Amazon's list price or "was" price, which can be set high to make a discount look bigger.

• Typical price is the middle of the prices it actually sold at over the past 6 months, and over the past year; we use the lower of the two, so a holiday season or a price spike can't inflate it.
• Prices include Amazon's clip coupons when one was on the page at the time. A coupon from before a price drop isn't counted, since Amazon often stops showing it after the drop.
• Prices from before anyone could buy the product (a placeholder before launch) are ignored.
• Prices that lasted less than a day don't count toward "lowest in a year". They usually belong to a seller who briefly had the Buy Box.

What we filter out

• Nothing to buy right now. There's no price in Amazon's main Add to Cart box (the Buy Box), so there's no deal to point you to.
• Too new to judge. Less than 60 days of price history. Without a couple of months of prices we can't tell what's normal for the product.
• Not much of a discount. The price is less than 20% below its typical price (see how we measure it, above).
• The price see-saws. The price has switched back and forth between two levels at least 4 times in the past 90 days, staying at each for 2+ days. When a product alternates between $20 and $30, $20 is half of its normal pattern, not a sale.
• It's often this cheap. It has been at or within 5% of this price for more than 20% of the past year. A price it sits at that often is one of its normal prices.
• The main offer is used. The price in the Buy Box is for a used item, so it isn't comparable with the new price history.
• Sellers and brands we've excluded. We keep a short list of sellers and brands we leave out, for example listings with AI-generated product images.
• It's been this price for a month. It has been at about this price (within 10%) for 30 or more of the last 60 days. By then it's the going price, not a drop. Deals also rank lower as they age (see ranking, below).
• The price flickers. The price has dipped to this level for minutes or hours at a time 10+ times in the last 30 days, usually when another seller briefly wins the Buy Box, and today's price is one more of those dips (or they add up to 25%+ of the time). By the time you click, the price has likely gone back up. If the price it goes back to is itself 20%+ below usual, the flicker can only help you, so we keep it.
• Low-quality art. Jigsaw puzzles and diamond painting kits. Nearly all of the artwork on these is AI-generated, and we can't reliably tell which isn't, so we leave them all out.
• Amazon already sells it at this price. Amazon itself has never charged 20%+ more than today's price in the past year, and the higher usual price came from other sellers. Buying from Amazon, you'd have paid about this much anyway.

How we rank what's left

• Discount (50% of the score): bigger is better, up to 50% off.
• Close to the year's low (30%): full marks at the lowest price of the past year, none at 20% above it.
• Popularity (20%): how many people bought it last month.
• Established brand (10%): brands that have sold on Amazon for 5+ years get full marks, brands under 1 year none. A brand that's been around has more to lose from a bad product.
• Freshness: after 14 days at a price, a deal slowly loses rank, down to 50% of its score at 30 days.
• Each list shows at most 2 deals per brand, so one brand's sale can't fill the page.

What the labels mean

• Lowest in over a year or First time this low since …, in green: it hasn't been this cheap in the past year, or only once, more than 180 days ago (a yearly sale).
• Occasionally at this price since …: it has come back down to this price 3+ times in the past 30 days. If you miss it, it may well come back.
• Dropped this low once / N times: it has been this cheap before in the past year; a fine time to buy if you need it, but not rare.
• Reaches this price fairly often: 3+ times, or 20%+ of the past year.
• Jittery (pulse icon by the price): the price has come back down to this level 2+ times in the past week, and it typically stayed there under 6 hours, often because one seller sold out and another's higher price took over. If you see a higher price, check back later.
• Short history (sprout icon by the price): we've seen under 180 days of prices for it, so its usual price is a rougher guess and we can't yet say how rare this price is.
• New: added since your last visit. Your browser remembers what you've seen; we don't.
• 1K+ (bag icon on the photo): how many were bought on Amazon last month, rounded the way Amazon rounds it.
• 3-pack · $2.78 each: for a pack of identical items, what each one costs.
• With 5% coupon: the price includes a clip coupon. Clip it on Amazon to get this price.
• Also discounted: other sizes or colors of the same product that are also below their usual price.
• Dropped 2h ago: when the price fell to this level. Checked: when we last saw the price. Prices change fast, so check the price on Amazon before you buy.

What you won't find here

• Promo codes and Subscribe & Save prices. We only list the price in the Buy Box, after any clip coupon.
• Paid placements. No brand or seller pays to be listed.
