Hello - I have a website that I am putting Add to Cart buttons on. All is fine, except for I offer a flat rate shipping no matter how many different items the customer selects. For some reason if the "Quantity" of the SAME item goes up, the shipping stays the same - that's good. But when they select another item from the same page...i.e. a blue short sleeve T-shirt, then a black long sleeve T-shirt, then a white hoodie - it adds the shipping 3 times (once for each item) instead of leaving it at the flat rate for all 3 items. Any suggestions would be great! ~Thanks~
