New to all this so bear with me!
At my local asda living store they were having a sale on some of the bedding, I managed to get a king size duvet cover and pillowcase set for £7.50 reduced from £25! Also got a king sized fitted sheet for £2.70 from £6.50.
Not sure if its store specific - these were from the Cortonwood store. Hopefully be some bargains elsewhere though.
They also had rails of sale clothing for £1 per item. Can't see any of this on their website so I think its instore only.
