How are the deals in this guide chosen?
Every product here is live in the retailer's own catalogue, price-checked against the retailer within the last few hours, and scored on the size of the discount and how long the price has held. The list is rebuilt daily as prices move.
Does Fazy sell these products?
No. Fazy finds and verifies the deal; you buy from the retailer, who ships, charges you and handles returns. Fazy may earn a commission from the retailer, which never changes your price.
