Partnership with shipping services
If your main issue is with shipping outside of the US, do note that there are forwarding services like Comgateway (or HopShopGo) and Border linx that provide you with US addresses for you to ship your purchases to. These services will then add a fee to have your item shipped over. For some of these services, you also have the option of accumulating several purchases to be shipped over at once, cutting down on overall shipping cost.
HopShopGo is a collaboration between Paypal and Comgateway
