Discount Glasses Frames Why Do Frames For Glasses Cost So Much?

Why do frames for glasses cost so much? - discount glasses frames

I recently received a pair of glasses that even after the cost of insurance and discounts on the sale, $ 290th I could be a buy for the Xbox 360 cheaper. Now I can understand why the lenses can be expensive, but my own pictures for $ 160 and were cheap compared to the other side of the store. Why are the frames are so expensive? I mean, I saw the metal complex works in the local craft store for a few dollars.
