SAINSBURY'S customers have been rushing out to buy outdoor essentials selling for just £1 instead of £18.
One savvy shopper took to the Extreme Couponing and Bargains UK Facebook group yesterday sharing a photo of the TU women's wellies.
Alongside a snap of the yellow boots with an £18 label attached was a second photo with a receipt showing how they cost her just £1.
She captioned the post: "My bargain for the day. Marked up as £18, went through the till at £1!!"
She added: "I had to double take when I scanned them."
Fellow savvy shoppers have commented on the post sharing their excitement for the woman.
One said: "Jealous," while another added: "Brilliant."
A third shopper simply added: "Lovely."
The women's receipt shows she found the wellies in the Holborn, London, Sainsbury's store.
You might be able to find the wellies at the same price in your nearest store, but you're not guaranteed to.
The boots aren't on sale on Sainsbury's website.
Of course, you should always look elsewhere to see if you can get a product cheaper.
You can use websites like pricespy.co.uk that let you compare prices on thousands of products.
Or you can use the "shopping" tab on Google to see what price other retailers are selling the same product for.
However, in this case we couldn't find any others selling the TU wellies for less than £1.
It's not the first time a shopper has managed to bag themselves a bargain in recent weeks.
Just last week, a B&M customer found a three-piece glass canister set selling for 10p instead of £9.99 - a whopping 99% discount.
Meanwhile, earlier this month Atkinsons was selling an air fryer for £10 down from £120.
Retailers sometimes offer extreme discounts on products to clear excess stock so you have to be eagle-eyed to catch them.
There are other ways you can find heavily discounted items in your nearest supermarket too.
Asda, B&M, Tesco and Sainsbury's all have scanner apps where you can find bargains quicker, for example.
There's also a number of Facebook groups where members share photos of bargains they've found while out shopping.
