No, I don't like it, but "In Rome be a Roman"... so, I tried my best, bargaining everywhere. I don't know (nor care) if I did good or bad deals! I just found amusing that, for them, it seems more important to discuss the articles than... selling them.
That's why sometimes I gave up and left, and... bought cheaper at the shop doors.
Remember: Bargaining is a cultural reference, and if you don't do it you will be spending your money and... shocking them.
