Don't know this person, but your right about Ebay siding with the Buyer in disputes. I've been buying and selling chips on Ebay for 15 years and have had a few disputes with buyers. I stand my ground, as best I can, and usually refund if I get my chips back. Then immediately bidder block said person. I've bought a good number of chips from you on Ebay and you are an excellent seller. I would not let this person sour you on chip selling. As far as Ebay goes, drop them like a bad habit if you think you should. You can sell on the board. Hang in there and Merry Christmas.
