This plug-in is formatted and coded well. The conditional logic is great. Unfortunately, it will not suit the needs of a large percentage of businesses that download it. It works for the sale of items of unlimited quantity. For instance, "Download .mp3 album" or "Purchase Warranty." However, it definitively does not work for add-on items of a limited quantity, such as "Add Tomato to Burger" or "Add Case to Headphones" because there is no option to check or subtract inventory. This is extremely frustrating and sort of a time waster. This can be fixed by adding an SKU in the backend and conditionally displaying the add-on if inventory is available.

Love it works great with no problems so far! Might take a little CSS styling, but other than it's great!
