$11 USD (~ $17.39 NZD) off $40 USD (~ $63.24 NZD) or More + 11% off @ iHerb

During the month of November, when a new customer uses your Rewards code, they’ll get $11 off their first order of $40 of more and you’ll get $11 in Rewards credit that you can redeem or save to cash out once you’ve earned $100 USD. For Orders under $40 new customers receive a 10% discount and you receive 10% of their order as Rewards credit. You receive a 5% rewards credit when referring existing customers.

This is more than the usual 5% I think it was? :)

Credit to Tarzan for the 11% promo code.
