+1 on getting them from my local optometrist. They are small and give me good service, and prices are within a few bucks last time I checked.

For some reason it seems like the only fair feild in 'medicine'. I ask how much service x or y is, and they tell me. Not like a dentist or care clinic where they won't tell you how much even a basic visit will cost. So I feel good about supporting my eye doctors.
