Here's an idea to generate some revenue: Some people might love some specific candy you sent. Let people buy packs of that candy through you.
Another reason I haven't done this yet is that I would need inventory control again. I was running an ecommerce store once and it does add a bit of extra work to make sure you have every item you claim to have and to be able to pick and pack them efficiently. Basically need barcodes and labeled shelves.
