Costs for eye exam and a nice pair of glasses?

I usually get my glasses from Costco because they are cheap and have very nice glasses and you can get an exam for about $40 and glasses about $60 all together an average of $100, but that is if you want a nice pair with a sturdy frame, you can get wired glasses for a cheaper price. But the glasses will come ready in about over a week, so you've got to be patient then, but the wait is rewarded. :)
