25% Off All Clothing @Tesco
In particular this gorgeous fleece reindeer onesie is £9, £10 or £11 (depending on the size you order) but you'll get 25% off that price when you get to the checkout.
Perfect for the countdown to Christmas, this fleece onesie has an embroidered reindeer face on the hood along with cute furry antlers. Can you imagine cosying up in this on Christmas morning? It also has a zip fastening and soft jersey cuffs.
I just tested the offer and got £2.50 deducted from my £10 order when I reached the checkout.
