Some frozen food or something that could be shipped through the mail would be pretty awesome haha. But I think you need to be very close to whoever you're shipping to because the food will spoil. Other than that I would like to pay normal bills in Bitcoin.
That is nice but I think its still hard to ship such products these days, its depend on the distance of course but it will never globally work out.
Maybe a sort of snack store, souvenir snacks from all kind of country'.s
