To be honest Calumet have done well to survive so long in a changing world. When I started in photographic wholesale Keith Johnson and Pelling & Cross were separate entities, the wholesaler I worked for closed down totally over a decade ago. Digital has made a massive difference for businesses. We were supplying Polaroid 5"x4" film to the tune of 50 boxes a week to one photographic studio alone (at around £10 per 20 shots iirc) film and paper sales were in the thousands of pounds per week, pretty much all gone now.
I have dealt with Wex and been very impressed with their service and product knowledge, hopefully it will be a good merger for all parties.
