GIVE your codes out people!!
If you have EVER ordered anything from iHerb.com you have your very own coupon code/referral code.
You need not do a THING except share the code with friends. When they use your coupon code they will get $5 off of their FIRST order and recieve their own coupon code/referral code. When they share the code, their friends will enjoy a $5 savings off of their FIRST order and your friend will earn 4% commission on the order placed (based on their order subtotal). It doesn't end there!! Because your friends' friend used his/her code and your friend got their code by using YOUR code, you will also earn 3% on your friends friends' order (subtotal). Have I confused you enough yet?
