Other affiliate programs don't share in the profits with active affiliates.
Other affiliate companies seldom allow you to profit of sales from more than 2 tiers of downline.
Very few of them have been in business 16+ years or made as many affiliates into 6 and 7 figure earners.
Other affiliate programs often come with high cost, or a ton of empty hype promising millions with little or no effort.
Keep in mind that if someone says they will build your downline and generate your sales for you the only thing they need is your money. If I am looking for affiliates to grow my business I want hard work not just a few upgrades here and there I want product flying off the shelf.
