This is just one of the coolest sites I have seen in a long time.
It is more geek oriented, than bargain oriented, but I love it!
You can go to any page on the internet. Put Aviary.com/ in front of the full URL address and presto, it takes you to their site where you can crop and design with that page just as if you had made it in photoshop.
OK, I don't feel like I am explaining this well, but I am putting it on my blog because it is AWESOME!
If you can explain it better.... please post a comment.
