I sent a PayPal payment on 1 Sep. 2008 Time: 13:17:05 and paid express delivery wich was £4.95 instead of free delivery.
Anyway i got a email from seller Tue, 2 Sep 1.00pm saying that Confirmation of the payment had only just came through.
I have never experience this before. i've always received paypal straight way. I have never heard of someone geting a paypal payment a day after.
