The rules for what lands on this site, and where the price you see comes from.
Retail discounts are measured against list prices, and list prices are fiction with a dollar sign. A product that has sold for the same price every day since March is not “28% off” because someone typed a bigger number into a field once. So we ignore the banner and look at how the product has actually been selling.
Deals are found with market-data tools that watch how prices move over time. Prices come from Amazon: every price on this site is pulled from Amazon's official data feed and shows the date and time we last checked it. If we don't have a recent Amazon price for a product, we show a “Check price on Amazon” link instead of a number.
A product is featured when our tools flag its current price as meaningfully below where it has been selling. When the price moves back up, the deal comes off the site automatically. Products in our Au Naturel and Corpus Naturale collections are the exception: they are listed on merit, sale or not, after passing the genuineness vetting described on each product page.
We rank featured deals with an internal score built from those market signals. We don't republish third-party price histories, so you won't see charts, averages, or “was” prices here — just the current Amazon price and when it was checked.
Every listing also clears a structural check before publishing: working product image, a functioning outbound link, and a valid listing. If any of it fails, the deal is held for human review instead of going live broken.
When you buy through our links, Amazon pays us a commission from their side of the transaction — your price is identical either way. That commission funds the site. It does not touch our picks: the ranking has no field for “what pays us more,” and a weak deal ranks weak no matter whose link it wears. Full details in our affiliate disclosure and editorial process.
