The reasonable ones.

Read the deals, run the math, click the buttons. If you find a bug or think a deal is wrong, tell us. The point of this site is to be useful; we can't be useful if it's broken and you don't say anything.

The prices on this site are recorded prices from real purchases we've made, snapshotted at the time the receipt was added. Amazon's prices move constantly — we re-check periodically but the price on Amazon at the moment you click is the price you pay, not the one on our card.

The calculator math is an estimate. Your hourly rate, your car's MPG, and the gas price near you are all moving targets. The defaults are honest middle-of-the-road numbers; tweak them on the deal page to see your real number.

We're not responsible for product quality, shipping problems, customer service, or anything else that happens after you click through. Amazon (or whichever retailer) is. We're a comparison site, not a marketplace.

Don't crawl the site to rebuild our catalog. If you want bulk access to the data for legitimate research, just ask.
