I use ebay a lot and have goods/bads.
Seller - it sucks in a lot of ways because the buyer has all the power. IE - returns for damage. Ok this is a lot of times pure BS. A buyer can claim this for anything and get away with it. Case in point - I sold a cigar lighter, a very intricate one not for beginners. I know my stuff, had it properly drained and labeled for shipment. Packed like Fort Knox. Buyer had a US address - freight forwarder. I did my part it was delivered. Now 45 plus days later buyer emails me that it blew up and caught fire. OK, so I ask - how? He says well it had a leak. SO I ask, how, damaged in shipment? So I have to inform him that the US postal insurance stopped the minute it was delivered in Florida. I did my duty. Unfortunately, what I think happened is one of 2 things - the freight forwarder damaged it OR this very "smart" individual didn't know what he was doing, put inferior butane, or screwed up the valve upon filling, etc. and blew it up. HOW IS THIS MY PROBLEM?????? Well, according to ebay it might be b/c item not as described or damaged. BS.
The positive is that its a world wide audience. I have noticed that my best success is when I set my price , don't budge and wait. It eventually sells and you usually for 99.9% of the time get a great buyer, of course, you only remember the unreasonable ones.
