I have to LOL, even though it's not funny. I have had the same thing over and over again...and always newbies who do it. I think the major problem is that people just dont READ the info in our auctions.
How many times have I put specials in my auctions, such as free shipping if they pay the same day. Then they pay the same day, and add the shipping. I have reached the point where if they pay the shipping when I said they didnt have to, why correct them?
I too have experienced the multiple item auction buyers bidding on more than one. "Whoops, I was just showing someone how I bought it, and accidentally bought another". "Gee, I tried to pay now, and bought another instead"
I tried to solve the probelm by forcing the buyer to pay immediately with Paypal...otherwise they cannot claim the auction item. But Paypal had a problem, and when the buyer tried to buy the item, they got a message from Paypal saying there was something wrong with my account, and I couldnt accept any payments at the time. Thanks Paypal for driving my customers away completely!(Its not like ebay refunded the cost of my auctions either...considering they emailed me to say the problem was fixed on the day after the auctions expired....LOL yeah it was fixed, the auction ended!)
