iHerb has a unique affiliate program. Once you open an account and place your first order using referral code MOQ651 you are entered into their affiliate program named iHerb Rewards. This is a fantastic opportunity to earn store credit and even a 2nd income stream from iherb.com
This is the best health affiliate program. You receive residual income until whenever they end the program. Each participant earns 4% for the 1st year from the people they refer, which doesn’t sound like a lot, but it adds up. After the first year you receive 1% until the end of the program. There is also a tiered reward structure that lets you earn between 1-3% from people referred by those you refer. It can be confusing but the iherb affiliate program is worth checking out.
