Why people buy goods overseas?
The main reason is lower price.
It’s a well-known fact that during sales season in USA you can buy quality stuff way cheaper (sometimes at 70%, 80% or even 90% discount.).
Furthermore, sometimes the thing you need is hard to find in your own country and therefore, you’re forced to look on foreign stores' websites.
But before paying for shipping, your customer has to find the right thing at a price he’s willing to pay for.
