Shoppers across the country are taking advantage of huge 70% off discounts as retailers reopen their doors following a three month lockdown.
Chains including John Lewis, M&S and Topshop are offering big reductions to win back customers, as millions of pounds worth of stock remains unsold due to the coronavirus pandemic.
But if you're shopping at Marks & Spencer, Martin Lewis has one more trick you need to know about - especially if you're planning a big shop next week.
"I've got a clever trick that will get you £99 worth of Marks & Spencer goodies for just £15," Martin Lewis explained on tonight's ITV Money Show.
"When you spend £25 in stores on clothing, beauty or homeware, you'll get a code to buy an 11-piece beauty bundle for £15," he said.
"And my team have calculated it to be worth a huge £99."
The bag has 11 items inside including make-up, skincare, hair care and fragrance.
It contains a mix of M&S-branded products and items from well-known brands - six of them are full-sized, and the rest are minis.
"The brilliant news is the deal is back for the third and final time from next Tuesday - so keep your eyes peeled. Last time it sold out within the hour," Martin explained.
To get the M&S 'Summer Beauty Bag' for £15, you'll have to spend £25 on clothing, beauty and/or homeware (excluding furniture and sale items).
So technically, you have to spend at least £40 at M&S to bag the deal.
But to unlock the saving, you'll need to wait until it's back in stock on the morning of June 23.
Once you've placed £25 (excluding sale) worth of items in your online trolley, you'll need to add the beauty bag to your basket.
Enter the code T314602, and it will be reduced to £15. Delivery is £3.50 on top, or you can collect it in store for free.
M&S says the beauty bag will be available in 85 of its stores, but make sure you check stock levels before you go in to pick it up.
