Print vendor not available

Hi, I setup my Photo Shelter website with a view to setting up print sales with Loxley Colour, based in the UK; as I have used them for personal work and am very impressed with the quality and trust them to produce the best prints for clients. It has taken me a while but now that I have finally come to setup sales I can no longer find Loxley Colour on the Vendor list. Has the partnership with Loxley and Photo Shelter come to an end does anyone know?

Many thanks, Kim
