Menalto Gallery2 shopping cart needed. I am currently using the Checkout module with Gallery2. This module can be modified, or switch to Zencart which is already integrated through another module, or I am open to other suggestions.
1- basic cart functions that also include item options (attributes) which can be dependent on another option (attribute).
2- item options which include a link to select another item as that option (attribute).
configurable attributes must effect price in basket or cart.
