I went to the location on 91st Ave and Thomas via the $39 groupon. I was really worried because of the terrible reviews I read, but I think those are for the other location, so avoid that one! My experience was great and I am happy with my purchase. Because the Groupon gave $200 towards exam and frames, the end cost is very reasonable. What I could expect to pay was explained before the exam, and the final total given after, no bait and switch. The staff were friendly and helpful and the doctor was very kind and knowledgeable! :D
