Hey everyone, I just won a Suntour Superbe front derailleur for $10.50 on Ebay and the Seller no longer wants to honor the auction. I was waiting to hear from the seller about a total including shipping but instead, got an email saying he's quitting ebay and to get a refund if i've paid already(seller only has 6 auctions in history). Is there anything I should do? This isn't the kind of post I wanted to kick-off with here but alas...
