Very friendly staff and open to questions, but do not expect a real bargain for your $15 for $150 value groupon. I was told $50+ superthin/ultra-thin lenses was mandatory for vision of -200 & more. Basic frameset is at least $120+. Eye exam is $75. Minimum total out of pocket still comes to around $120+50+75-150+15=- 110+tax. Versus I can get basic nameless brand glasses for $40 CAD or less overseas (eg. China/Taiwan/Vietnam)
