I ordered 2 pairs of glasses and paid extra for Rush delivery for an upcoming road trip. One pair was rushed and the other wasn't. I contacted Zenni to learn that they didn't offer Rush on the second pair, even though they accepted my payment for Rush delivery. I asked why they didn't tell me that at the time I placed the order, so I might have selected a different pair. No answer and no refund. Won't use these clowns again.
