I need these modifications made for CubeCart v3, so please PM me your quote for each mod. 1. How much would it cost to have product options also add on to the weight of the product for calculating shipping costs? 2. How much would it cost to integrate USPS Click n Ship into the cart so when an order is placed I can login, verify order, and print a label right from cubecart? 3. Would also like a mod so if there is only 1 item in a category then when a user clicks on that category it just goes straight to the single products page. Again, please quote each separately. Thanks
