Cannot review because 6 weeks later and stillno sign of

Posted by 5558299951893615447 on Dec 18, 2015

Iherb is becoming a bit of a joke lately. 6 weeks and no sign of my items. So how can I review this? Well I can't but I can review I herbs dismal attempt at fobbing me off and blaming the post. That total rubbish. One time iHerb was a pleasure to deal with, now their becoming a bit of a joke 6 weeks and counting for this item, but what's bothering me even more is I have 4 more parcels from iHerb. If you want to learn about patience, purchase from iHerb, if you want your items and stay healthy, well purchase elsewhere.
