Was it an "eCheque" or something like that? I've never figured out how to pay by that method, but when I've received them they take ages to clear.
Speaking of PayPal, I got an email from them yesterday saying I've received too much money and I've got to do some extra authorisation procedure or they'll suspend my account.
The tone of it is so threatening, they make it sound like you've done something wrong - when they should be saying "thanks very much for selling all that stuff and giving us a fat percentage of the proceeds"! :x
