I think the point I'm making here is it should be worthwhile to send the kit.
Unifi access points are so cheap, that second-hand ones "lying around" are not likely to be worth the cost and effort to ship internationally (or even nationally in the case of some postal systems). Something like a 10gig switch or whatever would be a different kettle of fish, as the residual value would make it worthwhile. For commodity kit like that, I think Tom Smyth is thinking more down the correct lines of approaching the manufacturer. I would also suggest approaching the higher-tier "authorised resellers" would be an equally good idea, as larger resellers higher up the food chain are often allocated a quota of free/cheap units. They are generally not permitted to dispose of the freebies for a defined period, but after that, they can normally do with them as they wish.
