What's up with the kids selling bottled water and chips in Dinkytown?

They've been there for months. Every time I go into Dinkytown these kids are selling bottled water and chips that clearly came from Sam's Club or something. I've seen them say it's for a fundraiser, but that doesn't seem true. Anyone know what's actually going on with them?

EDIT: I know that they CLAIM to be raising funds for a sports team, but that's very obviously a lie.
