I have been following the thread about "good condition" and "as-is" with great interest. As some of you know, I sell stuff from time to time on eBay. What you don't know is that I occasionally sell stuff at a local flea market. My selling rules for both are simple: everything is sold "As-Is" with no returns. Everything I sell on eBay is "As-Is" only because A) I can't guarantee the shipper won't destroy or loose something (happened once, took three weeks to resolve. The customer got his money back). No returns in case the purchaser buys something and then returns an identical but defective unit (think it happened once- I'll never know for sure).
I don't take credit cards for the simple reason eBay and flea markets sales are just a hobby for me. Cards are a hassle.
At a flea market or garage sale, or any auction I have ever been to, "where-is, as-is" is the rule of the day- why should eBay be any different?
