I would like to give current members the ability to purchase upgrades, e.i. custom designs. I don't want to make a separate signup form because people can just go there to sign up. Is there a way to make it so that the current member can just purchase another product without signing up again? How can I directly link to a product?
They can do it from within the members area- add/renew subscription. You can also make a upgrade link in this format: /amember/signup/index/c/Psignuppage8/?paysys_id=paypal&product_id=1-1&_qf_page-0_next You need to edit the signuppage id, payment system and product id. David
