cheap sunglasses

Did you know Amazon has a pretty decent selection of vintage inspired sunglasses?? I recently found this out by accident, while searching for some new sunnies this summer that wouldn't break the bank. I think I succeeded, after buying two pairs for $6 and $7 each! I've been wanting to try the popular cat-eye trend forever and now I can say I have...now I'm thinking about trying some round circle frames à la Lady Gaga or the Olsen twins. Maybe this pair or this pair?
