eBay most likely, in my opinion, took funds from the seller. They almost always side with buyers.
I sold some used Dura Ace pulleys to a Canadian buyer, shipping from California.
He got impatient when the tracking ceased at their midwest hub. From there it goes on to Canada.
I told him to sit tight, because shipments lose tracking after it leaves that hub (for international sales).
He filed for a refund the next day. The pulleys arrived ten days later! So he paid me for my shipping cost and fees.
He got nice $30 pulleys for eight bucks!
