I had trouble with some spanish guy. I won some old TIP CDs on Ebay & never recieved them. 3 months later he sent an email saying that he had been in a car accident & had been in hospital. He promised to send everybody who had been waiting for things, the items very soon after. I never got mine & all emails after that were ignored. By this point it was too late to post any feedback. I don't know if he really had an accident or not.
Another guy I bought a CD off from ebay also didn't come. He said it was probably the post, which it probably was as he sent me a replacement (not in fantastic condition but no problems playing) right away.
