Editor’s note

I look after this “COS” page. Offers come in from COS's own affiliate program and are refreshed every day; my part is the notes, the shopping context and following up when shoppers report a code that no longer works. In my experience, the biggest savings at COS usually come from limited-time brand sales and sitewide codes applied at checkout. Offer terms can change on the retailer's side, and some codes depend on your delivery region.
