Think you're getting value at Doctor's Valu Vision in Cookeville TN, Think again! the Buy one pair and get one pair free is not true. You'll pay twice the price for the first pair. It took three weeks for the glasses to come in. they promised 10 days tops. the office manager was very rude when we called to inquire about the glasses, they don't call you when your glasses come either, its ur responsiblity to contact them. we made three trips to cookeville for nothing. I will not use Doctor's Valu Vision again, and i don't recommend anyone else does either. You'll leave feeling ripped off.
