On clearance. Appears to be instore only (online price for single is still £14.97). Approx. size 122x61cm (single), 121x107cm (double), 3 heat settings, machine washable & tumble dry safe, extra foot warmth, tie cords.
Only around three or four of each size on shelf in Bradley Stoke store last night. Not sure what the availability will be like for other stores since it is clearance, but I thought it was worth a check at this price.
