I recently ordered Carradice bags from St. John Street Cycles in the UK. It has been a long time since I gave them business, due to the poor exchange rate and their diminished stock of NOS parts long vanished from the U.S. Maybe they got tired of competing with Ebay.
For whatever reason, they have very competitive pricing on Carradice, with Royal Air Mail included, and filled the order in about a week. The shipping seemed low, but I found out why when it arrived. Read about it Here
