Yes. Unused Rewards Credits expire 180 days after the date when they are posted as "Available" in your iHerb account.
Please note that the credit in your account falls under one of the following three categories:
A) You have been able to use your reward credit for purchases, or have previously received a cash back check by mail. You will once again be able to cash out at the end of this month and be sent a check, or use your credit for purchases. No need to take any steps now.
B) You have not shopped at iHerb during 2012. So as not to lose your reward credits, simply sign in to your iHerb account and shop as you normally would. As you add items to your shopping cart and you will see the credits being automatically subtracted from your subtotal.
C) You have shopped at iHerb recently, but the reward credit was not applied toward your total.
This means that you have already used up your $600.00 rewards credit allowance for the year 2012. Note that during each calendar year, rewards credits up to $600.00 are applied toward your iHerb shopping cart automatically.
Because of US tax law, we must ask you to fill out related tax forms if you have more than $600.00 of credit in your account.
