I think there are many upsides to a setup like that. Also legally, I think you pretty much wash your hands, since youre not spitting out a physical product. But who knows about US laws. Im in South America, so shipping is a huge deal to me when buying from different people, and I think LIttleJacob, located in Europe, feels the same way. So there's potentially a big international market for such packs. Very easy to setup, and very, very easy to sell. Again, best of luck :=)
