I get it at www.bitshares.org
There is a setup account button.

Once that's done, you selected Exchange page

and BTS currency on the upper right window.

On the right side, clickon the blue lettered "buy bts"

This is the easiest as you can do it via blocktrade. Just like buying more steem power. You deposit BTC or any other coin and that gets converted to BTS.

Thanks
