China has great same day logistics using poorly paid guys on electric bikes (so food and soft good delivery is very reasonable), but everything else is equivalent or a bit worse than the states.
Sorry your amazon experience has been so horrible. We live in Bellevue and it has worked out well for us. Sometimes we have to use the amazon delivery lockers at the 7-11 across the street, though.
Still...it's definitely not a non-starter. And with the exception of shipping updates which were non-existent once Thai post got their hands on the package, everything worked surprisingly well. All told, it took 7 days to arrive, shipping was ~$50 and customs was ~$65 on a ~$300 order that would have cost over $500 locally where the selection would've meant getting something that wasn't exactly what I wanted.
Not Amazon, but a recent experience I had. I wanted to order a kit from Vex Robotics. Cost of the kit was $80. Shipping from the US was $150. Supposedly it's available from a Vex reseller in Thailand so I contacted them and they quoted $190 for the $80 kit with a one month delivery time. So they are just ordering it from the US and having it shipped at a somewhat lower cost. I am not desperate for the kit so its a nonstarter for me. I can almost certainly find a serviceable substitute from a Chinese supplier who will ship to Thailand at a fraction of the cost.
