Instructions:Enter the discount code PA6P when prompted at checkout for 15% of sale items and new season. It works with the code SHD1 for Free delivery (thought it had been posted but can't find it).
Like most of the free delivery codes, these are meant to be for cardholders, but I got them to work without a problem, so should work for others too. Don't forget to go through Quidco for another 4%
Also P9KP for 10% off furniture and electricals.
