I ordered a lot of stuff from the US throughout the years. It takes at least a month to get here, and shipping costs from $50 (for the smallest items like Kindles), to $150-200.
So it's not really practical.
Looking at retail:
— the cheapest 3080 Ti 12GB I see is around $2500, the most expensive one is $3200 (there are 10 models in total).
— PS5: from $1000 to $1350
— 3080: from $2000 and up.
If you have the right connections you can get them individually with bulk prices, but it's not easy to do because of pervasive corruption.
(Unless Australia also has an oversupply...)
Nah. As long as you don't sell many, you can get away with just marking as gift and putting a value of 20 USD on the package.
I'd send close to 500 packages a month to destinations all over the world, and tracked items almost never go missing.
For those that do go missing, it's always to a few hotspots that I would simply avoid if selling an item this valuable (pretty much just Brazil and South Africa now; Russia and Italy are much better than they used to be).
So yes , "nobody cares" as long as you don't get caught.
