Many membership sites also want to sell physical products in a 'store' based approach. I know aMember can technically sell physical goods, but there should be a good solution so that you can add products in admin and have them specifically go to some type of store setup along with product page that looks good. Just a thought. Otherwise, many sites are forced to use [other shopping carts] + aMember.
aMember Pro has built-in shopping cart module, which may be used to sell tangible products. Currently it has all what necessary to sell tangible goods except 3 important parts: - shipping handling - inventory management - product options. We plan to solve these problems in near future.
