Our website has been organized into separate categories ie. 'Silver Jewellery' 'Handbags' etc. We would like to add the PayPal option to each individual item but we can only create a PayPal 'Buy Now' button to a margin underneath the item, not next to the item itself. Once this has been done, that particular item keeps appearing on the bottom of every page, including incorrect categories and other items. What can we do to prevent this happening? How do we add a PayPal button to the items we wish to sell, correctly?
