We bought these for our wedding. We purchased 10 pairs and the were misdelivered by UPS. Amazon tried to track them down, but couldn't. Apparently, they will maybe get sent back and credited. After that, Amazon would not help send a replacement order. So after an hour and a half on the phone, I'm still without glasses and only got voicemail for H2K. Bottom line, when something goes wrong with Amazon, Amazon and UPS can do nothing...
