That’s pretty cool to be able to do that. There’s only a small number of things that I could do to haggle pricing for things locally but typically it’s not worth it unless you are buying something a good size. I’m glad you are doing it and enjoying it! I know it can be fun, I did it a little bit when I was in Italy years ago!
To tell you the truth, bargaining for a long time isn't fun at all... it's just painful... which is why I try to wrap things up pretty quickly... it's true that often the sellers demand a price that's absurd... but if the price is just slightly higher, I just pay it off and move on
