Marks & Spencer will launch its second pre-Christmas 20% off Spectacular today, which should bring a much needed footfall boost to the high street.
Debenhams is also in the middle of a three-day Mega event with up to 20% off. The department store is expected to extend its discounting over the weekend. It held a similar event a fortnight ago.
M&S' discounts will be in addition to the 2.5% VAT cut, which was implemented on Monday.
The last M&S 20%-off day, which was held on November 20, helped to boost footfall by 5.06% according to Experian. However, shopper numbers dipped in the days running up to the promotion and post promotion.
A raft of other high street retailers are on Sale or are widely distributing "friends and family" vouchers offering shoppers money off.
House of Fraser has a five-day 20% off "friends and family" offer running this week.
H&M, New Look, Warehouse and Adams Kids are all offering 20% off vouchers.
Monsoon has 30% off and Burton has 10% off. Footwear chain Brantano is offering 25% off.
Daily Sale updates in the run up to Christmas are available from Patonz Compshop.
