I know there's a website...
http://www.zennioptical.com/.. with SUPER cheap glasses - like as low as $7/pair.. Granted it's online, so you can't really test them out on your face, but at that price, you could get several pairs and still spend less than elsewhere.. All they need is your prescription and retina measurement or something.. It looks like they also do returns, so if you just HATED a pair (or two or more) that's always an option... Good luck, though - I hate glasses shopping too.. I just got new ones last spring, but I'm going to try out Zenni the next time..
