It was China I learned that it could be fun. Until China, I had the guilt thing some people above have talked about. In China, it was just a battle - one I was always going to lose technically, but would still pay what I wanted for the items and so I could win too.
What I found hardest in China was going out from Beijing to the hinterlands, where they were not so used to tourists, asking the price of something and it starting below what I had already decided was my maximum price

I found it really hard to haggle hard when I was already happy to pay the price at the opening offer
