For those who don't want to swap and use the difficult to find website, you can use tokenshop as an alternative. There are plenty of swap sites out there with their own prices. And tokenshop too has their own stock and prices. So it's one of the places where you can buy the SmartBCH from BCH and FlexUSD there. Do give it a try if you want if you are in need.
