Apple will again offer discounts across its UK stores this week on "Black Friday," the mega shopping day after the Thanksgiving holiday in the US.

A notice on Apple's online store touts the one-day event, which is to start Friday 23 November on the web, and at the company's retail outlets later that morning.

Apple did not disclose any details of the deals it will offer, but if it follows past practice, the company will reduce prices on select hardware by up to 10%.

Last year Apple discounted most Macs by £81, which represented cuts of between 4% and 10%, depending on the model. Apple also reduced the price of the then-current iPad 2 between 8% and 9%, the second year in the row that it discounted its tablet.

Brian White, an analyst with Topeka Capital Markets, told clients in a note today to expect the same this year.

"Apple offered discounts across the portfolio (not all products) that averaged ~7-9% last year and we expect similar discounting this year," wrote White. "We believe this holiday season will belong to Apple as the product lineup has never been stronger."

As White noted, Apple refreshed most of its product lines in September and October, introducing the iPhone 5, new iPods and iPads, a 13-in. MacBook Pro with a Retina display, and redesigned iMacs.

Although the iMacs were introduced, their debut has been seriously delayed, Apple said, by supply constraints. Last month Apple promised that the new 21.5-in. iMac would ship this month and the larger 27-in. iMac in December; the former is still not available.

It's unknown whether Apple will trim prices of the just-released iPad Mini and fourth-generation iPad. Although the company has discounted iPads before on Black Friday, this is the first year where it's launched new models close to the holidays.

It's likely that other resellers will again match or beat Apple's Black Friday sales. For more info, check our Black Friday deals roundup here.

No surprise: Apple plans to reprise its one-day Black Friday sales. But resellers will probably beta its best deals.
