I suggest http://www.zennioptical.com. They are the least expensive place I have found online and they have a great selection as well. I have ordered from them several times, they can be a little slow sometimes though.
I would try FramesDirect.com. You can try on a lot of their frames online with their FrameFinder Virtual Try On System. If you have questions about what frames will work best with your face shape, they also have a Face Shape Guide.

Huge selection of frames, too.
