I found I got a lot better discount when I went around with my Japanese iaido instructors/friends. It cut the langauge barrier straight out, and it helped me explain what I was looking for...I also got warned off stuff that was overpriced! Maybe their 'iai face' got me a good discount as well! Never pay the first asking price anyway...
I picked up a couple of lovely tsuba that I don't feel bad about using on my iai swords, and used the boxes for some antique tsuba I picked up in the UK that I found unboxed at an auction. Thats what I call value for money! :D
