After my first glasses from glassesshop.com were delivered ok. I decided to order a second. These came with an incorrect prescription. More accuratly my correct prescription was printed on the box but the glasses themselves are not my prescription. After alerting them to this they have said "they are only $12 we do not want them back". That is the sum total of their customer service! There seems to be a big problem with communicating in English. Be aware that if you are spending a whole lot more than $12 you may not get your money back if there is a problem.
