CJM -
I used to make frame sliders for sportbikes on my lather from delrin. Sold many set son eBay. No problems. Then I sold to a guy from the military. Young guy. I sent them to him the day he clicked buy it now. They took more than a week to get there since I was in Canada, he was in the USA (customs). He took off for home for Thanksgiving and filed a non-delivery with me. He was on leave for a while and I eventually tracked him down and he had the product, told PayPal he wanted to reverse the claim even.
6 months later, after having my PayPal account locked I finally got it cleared. I got %50 of my money and lost a lot of revenue from not being able use PayPal. At the time no one else offered a solution like Google Chekout etc as others had gone bankrupt or would only cover their own auctions, not external auctions.
A total nightmare. You have to phone them, fax them and downright complain your butt off and they might, MIGHT get someone on it.
Phone them. Never email - phone, phone and phone and PHONE them until resolved.
