Smuggl

Smuggl connects shoppers with friends, or friends of friends, who are already flying the route they need. You browse catalogs from airports in many countries, or paste a link from an approved retailer, and the traveller buys the item and hands it over to you in person.

Your payment is held until you confirm the handoff, so nobody has to take the risk on trust. If something is wrong at the meetup you can report it instead of sharing your PIN, and the payment is refunded on the spot or automatically if the other person does not respond.
