If you're wondering why I'm 'selling' this: I opened a PO box and got a lot of requests for signed photos, it was getting expensive to pay for the postage on sending them to people and sometimes I get the addresses confused so I opened a store which allows me to collect all the addresses together in an easy to read format and also to cover postage costs :)
P.S. Before people call me out for selling these, I spent over £100 ($200) of my own money replying to fanmail that didn't send self-addressed and stamped envelopes like I asked. I also pay £100 a year for my PO box. So as you can see, it was starting to get verrry expensive.
