I know this might not be for everyone, but been looking on the argos site for a duvet set and they have this set half price at £12.49 plus you get another one free, so 2 sets for £12.49 which seems a bargain to me.
kingsize £12.49 for 2 sets
Double £9.99 for 2 sets
Single £7.49 for 2 sets
These are the details on the special offer:
Buy the Triptych duvet cover set and get another Triptych duvet cover set the same size and colour free. Offer is included in pack. Please note it will not show in your trolley. Offer ends 23rd July 2010.
So basically just add 1 to your basket & the free set will be part of it, no need to add 2, like I did lol.
