I need your posts to show my wife that I am not as extreme as you folks!
I used to eat at a cheap Mexican eatery when AA had a promotion for bonus dining miles before they implemented a minimum $ charge.
Also used a coupon at the same time and received thousands of bonus miles for $3 lunches.
I've rented a local airport AVIS during the weekend for $15/day to qualify for bonus miles, returned it within an hour, with an excuse that I changed my mind about my trip.
I've made my wife exchange an item she purchased on the 'wrong' credit card.
I've test driven a Buick for miles.
I'm currently eating a lot of Corn Flakes.
