Hi guys its me again, I have a few new base systems to sell on ebay but I am new to the game of selling stuff over the internet. I would like to know if there is a service that anybody offers ie. ParcelForce etc that will pick up the packaged PC, take it to where ever in the uk, then once the buyer has the PC they give the delivery guy the money for the PC, who in turn pay it into my bank account etc. I have looked around on the internet but I have had no joy. If there is no such service is there anybody that would be kind enough to suggest an alternative. Thanks in advance.

a service for ebay users.

It's called COD (collect on delivery).
Every postal service should have this to offer.
