"I agree, but if you're referring to folks saying that ebay will side with the buyer and force you to make a return, they are right. Ebay sides with the buyer no matter how ridiculous the scenario is. They can take the money away from you and not even require the buyer to return your item... happened to me just days ago. I haven't had many cases that I couldn't resolve myself, but in the few that ebay got involved, they ALWAYS have sided with the buyer. Most of those times I was the buyer. The times it happened when I was the seller, the buyer was unreasonable and trying to cheat me, so I refused to offer them more than a refund after they returned my item. They still side with the buyer."
I am very confused..... "Ebay sides with the buyer no matter how ridiculous the scenario is. They can take the money away from you and not even require the buyer to return your item..." but "Ebay has almost always given me fair treatment when I explained the situation and got a rep to review the exchanges of messages."

Seems to be a contradiction here.
It's part of being in business, not every transaction or customer is going to be easy. If in the end eBay makes it right, even if one has to make a few phone calls or deal with some aggravation, they are making it right. Nobody but YOU is going to be an advocate for YOU, and again if in the end it all works out I don't understand where the gripe is.
