Couponing automation

Probably stupid, but Jeffrey believed that with couponing, he could live on $1 a day for food and have plenty to eat (via MeFi). He blogged it for a month, spending less than $30 and eating rather well - while donating food to a local food bank. Then he kept doing it.

This intrigues me. A lot of the coupon game involves planning and "deal detection" that might be amenable to automation. So ... maybe it's a good target?

If so: SavingAdvice.com coupon database. Jeffrey's FAQ. An explanation of blinkies. There are lots of fora, of course, where heuristics could be gleaned.

Worth thinking about.
