Hey thanks for the info, it sounds sort of fishy to me too.

Here's a email he sent back to me when I asked him to let me know what post was his (I emailed a bunch of them)

Hey Matt,

This is my camera for sale : "Canon EOS-1D Mark II Digital SLR Camera, Lens and More". The price is $1,300.00 USD.
The process works like this, i will go at Royal Mail's office and let the package in their possession and start the process, they will notify you about this and send you an email with an invoice with the tracking number and the instruction on how to complete the transaction. You'll have to send them the payment
for the items, after your transfer is verified the package will be on his way to your address, You'll have 5 days inspection period from the moment you have the package. If you're satisfied with the purchase you can instruct the to release the funds to me If not, you can return the items and Royal Mail will make
a full refund minus the fees to return the package.
So if you want to make this happen please provide me your full name and shipping address. I will support the shipping and handling cost and you the fee to send the money to Royal Mail.

Thanks,
Stan

The idea of sending payment sounds pretty much like a scam to me. But I don't really know how Royal Mail works... If I was to mail something across the ocean I would do that too.... What do you think?
