Dphie and Tiffany's

So my roommate just got home from our convention and told me about a new partnership between Dphie international and tiffany's & co! Apparently we get like a discount when shopping online through our website and they're going to come out with a line of Dphie jewelry...pretty sweet!

I had never heard about a relationship like this between a sorority and brand, and I was wondering if any other organizations had something similar?
