I'm new to this whole website building so please bare with me. I built my website and I need to add a shopping cart program that can use authorize.net payment. I have the product pages already made up individually with buy buttons, images, and descriptions. What shopping cart would be the best to integrate with this kind of site? From what I have seen it seems like all the carts generate the products for your site with buttons, price, drop down menus, etc. But I dont want this. I just need to add drop down menus for product options and link the buy buttons to the cart. hope this makes sense. help is much appreciated.
