The wonders of eBay...

I won an auction on eBay last night. At about 10:30pm I went online and paid for the item using PayPal. Its a surround sound speaker set, in case you're interested. It'll be sent to me by ParcelForce. At 11pm I got an e-mail from the seller saying it had been dispached already!

I'm not entirely sure I believe that e-mail. Where is there a post office open at 11pm?
