I also buy and sell on eBay. I hate the way we sellers are nickeled and dimed to death, esp. with the Paypal fees. Sometimes I don't list Paypal in my ads, and am happier to take personal checks if the buyer feedback is over 25 or 50 w. only positive feedbacks.
Another tip: When I've seen something on QVC, or Infomercials that I might like, I go first to eBay. I have bought the same new clothes on eBay that are selling on QVC ...and saved a lot of $$.
eBay is definitely Buyer Beware; read the fine print. I try to keep my ads simple but cover all bases. Some Sellers ads get so wordy that I end up skipping over them and move on to someone else.
