You can use your iHerb.com "rewards" in two ways. You can use the rewards as credit (dollar for dollar) applied to your own iHerb.com orders or you can choose to have the rewards sent to you as cash.
You have to accumulate $300 before you can cash out.
You continue to earn the above rewards for 365 from their first order. After that 365 day period, you will still earn 1% of any order they ever make.
The only downside so far that I can see is you have to use or cash out your rewards within 180 days.
There have been time periods where I did not reach $300 and I hadn't ordered anything and have lost the reward/credit.
I will not let that happen again. If the rewards are not coming in, I will just apply my credit towards the many items I love from iHerb.com....now, Passion Tea. :)
In the spirit of not losing my iHerb rewards I ordered supplements I needed anyhow. Calcium tablets and EFA capsules and some other items and recieved them for FREE.
