I was thinking of visiting some flea markets in my travels to Europe this year and I'm wondering how will the fact that I'm a tourist influence the prices I'll get when shopping. From what I see most local people tend to charge more when dealing with tourists, especially if the price is negotiable, like it happens at the flea market. I was thinking that a good idea would be to find some local people and take them with me at the flea market, maybe this way I'll get a good price for what I buy. Anyone has experience in negotiating with the seller? Some tips?
