OK, thanks; got it! Do you have any recommendations about figuring out a "good running [local] optical"? Are there particular things to look for or ask about, beyond price? Or is it more a question of word-of-mouth recommendations, etc.? Like anything else, I would say word of mouth. Find a place that you get referred to by a friend if their mother, father, cousin, brother sister, girlfriend and everyone they know goes there. Chances are there is a reason why. And don't go on suggestions like "their decor is so elegant", "they always give me a bargain", "I never paid retail prices there". Just be weary about "too good to be true" deals because chances are, that it is. Best of luck hunting!
