Those codes are for 10% off anovos.com. when you place an order they give you a new code.so whoever used those codes should be be posting the codes they received to keep this going. I was going to use one for a phasma helmet but now 8 don't think I will. I don't want to give them the money for a year or more before I receive the helmet. I don't think they will get that helmet shipped by the quoted time frame of fall 2016. They have already missed other projected dates on other items.
