So I saved a couple of bucks, or did I by going to Sam's Optical.  The optometrist is only there on Saturdays, so they can't confirm your prescription unless he is there?  When I asked for my written prescription, they wouldn't give it to me and I was standing right in front of them because the Optometrist wasn't there.  Also I ordered some contacts, and when I went to pick them up, they couldn't find them.  I insisted they keep looking and half an hour later, they finally located them.  By the way, they had called me to tell me they were in.  Now I realize their prices aren't that good anyway.  Don't waste your time, saving what isn't that much money.
