Buy an Old 97's cd, build a house

Here's an opportunity I learned about when we bought a copy of the new Blame it on Gravity CD at the Old 97's show the other night. For every 234 CDs they sell, a sign at the merchandise table announced, someone in an area hit by Katrina gets the materials they need (about $3,000 US of lumber etc.) to build a whole house. A small house, but a house nonetheless.

Only thing is, on their online store, I don't see one whisper about this promotion. Maybe you can only do it by buying a CD from the merch table at shows. That would be too bad -- this is a great idea.
