Carpetright have got a sale on with 20% off 100's of carpets but if you spend £250 they will give you another £50 off. It is a voucher in paper. It works out you can get a carpet upto 50% off then an extra 20% off then £50 which is equall to another 20% off. I've been into the Beverley shop (East Yorkshire). Dont know if it is Nationwide. I think it even covers rugs and underlay which they dont normaly do.
