I used to buy a lot of electronic/luxury stuffs to sell in Asia. I buy them, and my old buddy would hook me up with Asian buyers (from China, HK, Vietnam... etc). I remember lining up in those cold rainy nights.
It was good money, I think I used to make easily 8k+ a year while taking no more than a few days (the total accumulated time) of trouble.
But then I didn't need to file taxes, so I never worried about CRS coming after me.
