Heres some stories as a Seller. I got into ebay at around 13 and have been using ever sence. These 3 stories I will share all come from me "using" my moms account.
I sold a hydroponic growing system on Ebay. I had to use a fairly large box to put it all in.
I recieved negative feedback saying everything was broken. however I never recieved a notice for the guy to refund his money. I had a 7 day return policy and still nothing. So after 7 days i contacted ebay to have them remove the negative feedback. They told me they couldnt do anything about it. I was pissed as hell because I know I packaged those items right. So i pretty much just kept bugging ebay to take a look into it. After about a month i notice my feedback went back to 100% turns out someone did look into it. They guy was going around leaving bad feedback and trying to get refunds for expensive stuff. I learned several lessons that day.
1. take pic of stuff before u send it out.
2. pay the couple $'s for insurance
3. If you know your in the right keep bugging ebay.
Second Story... When the 360 came out I sold my gamecube and all its games. I sold it for what i thought was way more than it and the games were worth(~300). After selling it I did the usual steps to send the info to the buyer. I got an email after 3 days saying they will pay me next pay check... I knew at that point i was going to struggle to get my $ for my item. So i hurried up and offered it to the second highest bidder who declined. A week after the item sold I sent another invoice. I wanted to relist the item however my mom told me to wait for another week and see what happens. Being my mothers account i said ok. After a week i got an email stating, "Im soooo sorry my mom recieved a brain tumor and she cant pay your right now. However when she gets dismissed you'll receive your money..." I sent a reply "Im sorry to hear your mom has a brain tumor however she is still under contract to pay me and I need my $...'" at this time i already have contacted ebay and going threw the no payment stuff. Within 12hrs i received my money.
I learned people will say anything to get out of payment?
No real big buyer stories other than I ordered the one legit item from a GBA counterfeit seller. recieved my item and the $ back b/c ebay closed his account.
