I have vending machines and things that go in are dated and you can get in big time trouble for selling outdated product. If these sandwiches have any decent flavor, the traveling public will go for them. There is that tuna and chicken salad with crackers and this cn't be any different from that. I would try it at the very least. If someone had told me 10 years ago I could sell bottled water at the rate I do, I would have called that crazy.
