That would work I guess. I tried a discount optician......not mail order....years and years ago, and the glasses were so bad I've been afraid to try anything other than a regular optician.
You, and most every other person I know. It takes a leap of faith, but....
When you KNOW you are getting charged $300 for a pair of frames that cost at the most $9 to make.....

I don't mind paying for good lenses, but the frame prices at the local places are really, really, well....
