I would like to offer PDFs for sale to download, but I can't figure out how. Specifically, these PDFs are knitting patterns. I have a merchant Acct with Paypal and have generated the code for a "buy now" button. I have a WordPress.com blog. I have created the PDFs... I have uploaded the PDFs to my wordpress media library. Now I just need to connect them all correctly. Ideally, I would like to set up a page where there is an image of the PDF with a "Buy Now" button under it. The user would click the button, enter pertinent information, and then at the end of the process, the PDF would download to their computer. Seems easy enough, but alas, I am lost. Please help!
The blog I need help with is theknest.wordpress.com.
