Checkout Candy for Zen Cart now includes a one click buy button for products without attributes that are displayed as possible upsells. The principle behind Checkout Candy is simple: if you have created a Zen Cart Better Together linkage where one item is present in the cart and another is not, you are encouraged to buy it on the Shopping Cart and Shipping Pages. For example, suppose you create a PROD to PROD linkage between product 3 and 10. If product 3 is present in the cart, and the customer goes to the shopping cart page or the shipping page, they will be prompted to buy product 10 (and shown the terms of the discount). Naturally, this goes well with Discount Preview.
