I ordered something from AliExpress recently, and I selected to have it shipped from Australia. Fast forward a week and I get an unexpected Amazon delivery that has my AliExpress order inside. It's from Amazon Commercial Services and was delivered by a courier that (from my experience) only delivers Amazon packages, so it wasn't just a seller reusing an Amazon box. I was worried that I'd had a brain fart and forgotten that I'd ordered something and reordered it from a different site, but definitely no sign of this in my Amazon order history.
It doesn't really bother me, I am just curious about how this works. Has anyone else had this happen? I'd be surprised if Amazon and AE have an arrangement for Amazon to fulfill Australian AE orders, but I could be wrong. More likely I'm guessing the seller has storefronts on both sites, and somehow processes an AE order as an Amazon order? Would be interested if anyone has any insight on this.
