I stumbled accross these great prices when I was looking for some wallpaper on the internet. Most of these I have seen in B&Q for £20, and in my opinion look great!
Graham & Brown Drama Traviata: Brown or Cream - reduced from £16.99 to £2.50
Graham & Brown Linda Barker Adorable: Cream - reduced from £18.99 to £2.50
Graham & Brown Linda Barker Grasscloth: Cream - reduced from £18.99 to £2.50
Monsoon Chrysanthemum: Damsum - reduced from £19.99 to £4.99
There were many others also reduced, and P&P is only £6 per order and free if you spend over £100.
