OneDayOnly sale, checked

How OneDayOnly sales really work

OneDayOnly runs daily flash sales, and the model is built on urgency: one price, one day, a countdown. That format makes the was-price especially hard to trust, because there is no shelf history to check it against and the brands are often unfamiliar.

We keep these at arm's length for that reason. During big events like Black Friday the site does drop genuine, fast-moving deals, and that is when it is worth watching, but day to day the inflated anchors and unknown brands mean you should lean on the price history harder here than anywhere else.

• Treat the countdown as marketing. A genuine deal is still genuine if you take an hour to check it.
• Unknown brands carry no price history, so there is little to verify the saving against. Be cautious.
• The honest OneDayOnly deals tend to appear during major sale events rather than on a routine day.
