I am outside US and have used them to ship internationally because they are one of the rare retailers who will ship delivery duty paid, avoiding local UPS/FedEx/DHL offices charging 30-60 USD just to do customs processing (local ~30% customs fees still come on top of combined shipping and item prices). Their international shipping charges have gone bonkers recently though too (what used to be like $70 for an ultraportable laptop is now like $200+). Thus I am bound to Amazon.de more but there's a smaller selection.
I also temporarily sign up for Prime when I visit US (usually for a week), but recently, unless I order on Sunday of my arrival and deliver to one of their lockers, "2-day shipping" or even extra paid same-day-shipping won't arrive by Friday to my hotel (last few experiences in Boston, MA).
Due to only "delivered by Amazon" products having delivery-duty-paid option, I avoid some of the risk of new Amazon, but I need to be extra careful when shopping while in the US.
