Your best bet is probably Camden Lock Markets on Sunday. ( London ). It is a zoo, but there are vintage dealers. Cds or Vinyl are much more expensive in the UK than here- there are vintage record stores in London- use google- but again they will probably be more expensive than anywhere in the US.

I would strongly suggest posting this question on the Thorn tree website/ Lonely Planet. Before you post a question.read for a while to get a feel for thre site.. Basically we (responders to posts) like the questions as specific as possible, i.e. " I am going to London and would like to look for markets/or shops where I can buy vinatge clothes" or whatever it is you want to buy.

I travel alot, and use that website to ask questions. If they are precise you'll get some good advice.
