Good question.
first why we make A2A friends,Whole SFI affiliate are bound as a one family known as SFI family. If we share with each other how we improve our business then easily we grow with SFI growth.
One thing our PSA are CSA of another affiliate. Their nothing any hidden technology that we share in our group only.
In ECA if we share our business technology with our A2A friend then both we are successful.
HELP OTHER GOD HELP YOU.
