So, my 'shop' consists of a few items that are available only to club members after login. The shop (Chandlery) does not show up on the public menu, only on the Members' menu. I ended up with a menu (I believe created by hikashop) and a menu item that I created for the Members' menu. I've attached screen prints of both.
When the member logs in, they will see Chandlery on their menu. If they click on it, the cart module displays but the products do not. I've made a screen print of that page as well. I've done so much fiddling around with this at this point that I'm no longer sure what I did!
