WEX Photographic 15% off filters black friday-15%Get code & visit site
Browse site and code is displayed where discount applies. The stand out discount IMO is on Lee filters. The Lee foundation holder has been reduced to £50 and the discount code still applies, and the code also applies to the adaptor rings which are difficult to get hold of at cheaper prices. There's other black friday deals but this seems to be the stand out one to me.
