Sallie Mae: Eating Out to Save Money?

Although Sallie Mae has been spared the brunt of the negative media attention reserved for her siblings Fannie and Freddie, based solely on rhetoric, she may not be any better.

I recently received an email titled: "Eating out can help reduce your student loan balance," encouraging me to eat out in order to pay off my student loans (which are still accumulating). While it is obvious that the email is referring to a system like credit card points, wherein purchases at certain vendors lead to points that can reduce one's loan balance. But still, to suggest that eating out can save money in any capacity seems rather misleading- almost as misleading as some of the tactics used by the demonized mortgage lenders.

Thoughts?
