Most of the selling I've done on there has been by my son. He ran into some folks who wanted to return items due to buyer remorse. A couple switched out the items and did returns. People trying to do charge-backs have caused him to loose at least 3 accounts when it was no fault of his own. They either failed to read the description or didn't look at all the pics. eBay is not like Wal-Mart.
Of the handful of cards we have sold, no problems with those buyers. Those buying toys either new or used, well that's another story at times. It's just too much hassle for me, I'd rather stick to buying.
