I spoke with Photobox everything is ok there. You have to have a Photobox account; it's free and simple to set up. You can't make a payment without being set up on their system.

Also, an important factor when ordering before you get to the payment window. Follow the trail and select the size you want and place the order. Go to 'view the basket' wait for next window and then select the box 'check my prints'. This will show you a thumb nail miniature, (here's the really important bit) check the box 'shrink to fit'. It's imperative you do this or, depending on the size you choose, the top and bottom or the sides could be clipped. This way you get whole the poster.
