Lidl is participating in Black Friday for the first time this year, with a Sale that launches on November 23.
It marks a step change for the discounter, which has never before run a Black Friday event.
Lidl said it will be slashing the price of many products by as much 75%, with deals across wine, meat and electricals.
The event will go live next week in stores, but offers will not be available online.
Lidl UK commercial director Ryan McDonnell said: “We’re pleased to be taking part in our first ever Black Friday promotion. Providing our customers with everyday low prices is at the heart of what we do by offering a selection of highlight products at incredible prices.
“This is a highly anticipated event in the consumer calendar, especially as households turn their focus onto Christmas planning, and we know our fantastic promotion will not disappoint.”
