I know of several instances where someone was selling something on ebay. The sent the item, recieved the payment via paypal and then suddenly the buyer decides that there's something wrong with the item (even though it's exactly as advertised) and puts in a claim to ebay that goods were damaged, not as described, never showed up etc. The payment is almost immediately (and without much, if any correspondence with the seller) removed from the sellers paypal account.
This hasn't just happened once or twice, but many times.
So, does anyone have any alternatives to Paypal ?
