I feel like there's a huge business opportunity for a pack-and-ship franchise on the non-secure side of airports. Have a big display of bags/envelopes conceptually like the Priority Mail flat-rate envelopes/boxes. If you realize you brought a local sauce, or a souvenir pocket knife, and can't check it, you can just toss it in one of those bags, seal it, write your address on, pay a modestly extortionate price, and it shows up at home a few days after you get back. By making it flat rate, they streamline purchasing flow and avoid hassle of people trying to optimize what they send back while on the checkout queue. I could also imagine it directly competing with the airlines' excess-bag charges-- if you're staring down the barrel of a $150 "third checked bag" penalty because you got something special abroad, being able to slap a FedEx sticker on your suitcase full of dirty clothes and pay $75 is a compelling value.
