Resellers can be bad. My company knew of well-known resellers who re-shrinkwrapped software that was returned, thus causing customers to claim that our software had viruses in it. We of course would have known instantly if we sent out software with viruses, since our phones would have been ringing off the hook, and not from software from only certain resellers.

On a different subject -- the new management of eBay is just plain evil and should be avoided. I'm looking forward to the rise of a really viable alternative auction-related site.
