Every hour we compare the same product, matched by barcode, across Best Buy, Amazon, Walmart, and Target, and list the cheapest new, in-stock offer first. No price games, no marketplace sellers.
Matched by barcode, so a look-alike never sneaks in. The lowest new, in-stock price is listed first, whatever it pays us.
Discounts are measured from the lowest list price any store reports, so an inflated “was” price never makes a deal look bigger.
A product joins the deals once it is meaningfully under list at a store that has it in stock. Checked every hour.
