Don't worry rich,he probably just paid with E-check which is funds from his bank. its super slow thru ebay,but it will go thru(its reliable).
It will probabaly take even more time since theres currency conversion also.
no need to worry anyway,theres buyer/seller protection thru paypal.

If they've paid via echeque then paypal recommend not sending until it has cleared and so do I. The payment can still be reversed if the funds dont materialise.
I accidently bounced a payment to someone when my pre-paid credit card allowed a paypal payment to someone without enough funds in the account. A week later the payment was reversed and I'd received the item by then. Made a manual payment of course to make good but as far as the vendor was concerned, they had received an instant payment only to have it reversed a week later.
