check_deal
shallowcom.vouchernaut/deals · Verify this server
Whether a product's price at a UK shop is a real deal, from Vouchernaut's own record of that shop's prices: pass a product page link from the shop, a barcode, a product's name or a `ref` ("<store>/<product>"). Gives the verdict on today's price (lowest we've recorded, no change, cheaper before and when), the shops selling the same product for less today, and a tracked link to buy. Says plainly when the shop isn't one whose prices are tracked. Never uses shops' own "was" prices or RRPs.
