Straight line. No games, no tricks, no bonuses you will never qualify for, everyone can understand and explain it.
I don't do 1up or 2up, binary or split legs because every referral cost money or time to generate and should pay you now under any condition that involves a sale of product. Products also need to be a real value not something over priced to pay for the pay plan and only bought to have the right to make money.
In other words a real network marketing company not a MLM Pyramid Scheme trying to call itself something different.
