iHerb has 11% off for Single's Day, slightly better than the 10% off offers we see now and then.
Starting from November 9th at 8 A.M. PST to November 13th at 10 A.M. PST, iHerb is offering a special 11% off coupon code for any order over $40 USD (AU $54 approx.)
Terms state that it starts tomorrow but it seems to be working already.
