Right. But at the same time there was issues with paying (nothing major, but still an inconvenience) and on top of that, if it was at a store the difference would've been noticeable. The problem here is that you are really at the mercy of the vending machine. While the company may want to prevent buyers remorse (or even taking advantage by buying a gadget just to use for a flight then try to return it), you can't expect people to be comfortable buying anything that costs a decent amount (for me that would be > $20) without being reassured that if it isn't what they thought it would be they wouldn't be charged.
