I have ordered twice from Zenni and am happy with the glasses, the delivery time (less than promised time), and the PRICE! They are upfront about being based in Hong Kong. Even with the add-ons (anti-reflective coating) the total cost is so much lower than anywhere local (eg. 3 pairs for under $50 both times I have ordered). Be aware that if you have a complex prescription, it may be harder to get the prescription and adjustments just right.
