I bought several pairs of eyeglasses from GlassesUSA and was happy with them. The last pair, however, was defective; the lenses shrank or changed shape and would no longer stay in the frame. They were two months old, and I used them for a spare. This isn't why I am giving a one-star review, however. The one-star review is for GlassesUSA refusing to replace the glasses. Instead, they offered a replacement at 50% off. That doesn't seem quite right, considering the glasses were 100% defective. In my opinion, a company that decides it is okay selling defective glasses to unsuspecting customers for 50% off is a dishonest and unethical company. At the very least, this 50% replacement policy was designed by a very dishonest person. GlassesUSA missed the mark for me, and until they can rectify the situation, I will shop elsewhere for eyeglasses. Caveat emptor...
