I do a very nice automatic aw2k email when I post feedback. It includes tracking info (I cut/paste all tracking numbers into aw2k), a big "thank you", and an email link should there be any problems at all. I also mention that I've given them postive FB, and that I hope they do the same after their item arrives.

If someone is having a problem, quick and friendly resolution seems to be key to avoiding bad FB. Most of the replies I get are extremely positive. I think buyers like the pro-active offer of help - it puts them at ease before they've even seen their item.

It works for me. 3000+ FB, 2 negs, 2 neut, 4400 pos. over 7 years.
