I've always liked Christy towels as they are great quality and if like me you try and buy British, some of their towels are even still made in the UK (the Embrace with Silk, Renaissance Egyptian Cotton and Panache Pure Cotton are all UK-made).
They currently have 50% of their "Tokyo" range of towels and "Capture" bedlinen, and 20% off their "Escape" bedlinen and the UK-made "Renaissance" and "Panache" ranges.
They also have 10% Quidco cashback, so you could get these great quality towels at at even bigger discount. If you use GreasyPalm, another cashback site, you also get 10% cashback but they have a permanent discount code of 20% of the entire range - it doesn't work with items already reduced but if you want a full-price product, you can get 20% off - don't know if it works if you don't have a GreasyPalm account or not I'm afraid but worth a try.
