Just so you know......
 

I live in Michigan. Here, at the Farmer Jacks grocery store you can register, and everytime you buy groceries you get a Northwest airmile for every dollar you spend. So you use your credit card you get two air miles. Also today, a friend got an offer from Sprint for 30,000 air miles for Northwest to switch over. Too bad I already switched to MCI about a month. Anybody get anything like that??
