The thought of having a machine where we can store a "description" of what we want to sell. Limited to lets say 5 or 6 items. Would be great.. God knows we get squat for selling item back to machines! But this idea would offer people to see what other people have for sale and can buy it cheaper then buying it at a machine.
The only thinf that would have to be worke out is how the person looks up the item.
