Hey Gary, thanks for talking about Brave, I have downloaded it, but not really used it yet...I will make an effort now.
I use B2B sites for ordering merchandise, for retail...and if what you are talking about is the same basic platform, I sure hope they have done some Major upgrades...because the ones I have used stink.
They have gotten better over the years, but wow, not so user friendly.
In a world without privacy, Brave is a good tool for the world, as is the DuckDuckGo.com search engine. These tools still need to get better, but they are a start :)
