Kyoto Flea Market Bargain Or Discount At Flea Market?

Bargain or discount at Flea Market? - kyoto flea market

I have to go before, at flea markets in Tokyo and Kyoto.

Are the prices fixed or are in a position to negotiate?

If the seller and says a higher price, because I am abroad?

If you can negotiate, ask for advice on what to say.

Thank you. I would like to know beforehand what to avoid rude behavior, negotiate, if it really is a common practice. Thank you.
