Ah, I wasn't aware there was a difference between echeck and bank transfer.
Are you sure? I assumed the same thing until a week ago when my friend payed me back for a video card and he used the bank transfer option in paypal, i was surprised when I got the $400 instantly and he confirmed it hadn't even put an auth on his bank account yet, i went on to spend the money 5 minutes later with no problem. Not sure what happened there...
That was not an echeck he sent you that is what happens when you have credit card linked to your paypal account and you send bank funds the receiver gets it instantly. It used to take Paypal at least two sometimes three days until they took the money from my bank account when sending that way.
