You can sell your printed publication(s), along with any items you deem suitable, to your post(s) using an online payments service such as PayPal. You will, of course, need an account with them in which you set up your details and create "Buy Now" and other buttons, which you will use in your post(s) to sell your items. All you then have to do is add the code they provide near the photo of your item in the "Body" text panel – and you are done!
