Axel: My experience is that Amazon’s implementation of various bans (1) takes a while, (2) is imperfect, and (3) is even more imperfect with non-Amazon, third-party (particularly out-of-their-garage) sellers. If you crash around a lot, eventually, someone somewhere will ship you what you want. If not on Amazon, then on eBay.
One shipping hint we almost all know: you can send Amazon packages to “David Thomas, General Delivery, Lone Pine, CA, 93545” although I’m usually using, “”David Thomas, General Delivery, Adak AK, 99546”.
One shipping hint fewer people know but that I’ve used sometimes is, “David Thomas, guest staying 12-12-2019; Hold at Front Desk; Los Angeles Airport Hilton; 5711 West Century Blvd, Los Angeles, CA 90045” if you’re flying somewhere.
I’ve also left bear spray and stove fuel for BPLer’s flying to Alaska – either at their AirBnB or at some point along their travels (say, in a plastic bag, under some rocks, right behind the Milepost 231 sign on the Parks Highway). You could put out such a request prior to a trip.
