For Example: If you are the 3rd Brand Partner (Partner C) to sign up for your ad slots and you buy 3 positions, you will receive the 3rd, 4th and 5th leads initially generated.
After all Brand Partners have received their first set of leads and the rotation starts again partner C will again receive the 3rd, 4th and 5th leads generated.
All leads are distributed in the order that each Brand Partner has purchased their advertising slots for each advertising slot they have purchased.
