Anecdotal: i ordered from goggles4u for the first time this black friday when they had a similar sale. Wife and I ordered 5 pairs of prescription eyeglasses, including one prescription sunglasses for $70 shipped. We received all 5 in about 10 business days.
4 of the 5 glasses the prescription seemed right on. The 5th the prescription seemed a little off but not sure if its just because of the shape of the glasses/lenses. The sunglasses came out perfect, however the temple of the sunglasses arm had large branding that wasnt in the pictures online. Luckily it scratched off pretty easily. Overall we were very pleased with the items we got for the price we paid.
