I have been buying from Calumet for some time, both online & in their London store. I always find their service to be very good. They stock a good range, and cater for everyone from those starting out in photography, to full time professionals. On a negative point, they do need to watch the price they charge for SOME of their equipment though, as I have found some items to be very uncompetitively priced at times. They do however normally match those charged by competitors to be fair, although this puts the onus on the customer to do their homework before buying, rather than instilling confidence that they will alway receive a highly competitive Deal. Calumet will continue to be a main supplier of my needs, but for this reason, not my sole supplier.
