Thanks for all the comments, folks.
I did another (very) short segment on the Today Show this morning (7/9), just before Lady Ga Ga performed her free concert in Rockefeller Plaza and a sudden downpour broke out. I think there's an ancient Mayan legend that says when Lady Ga Ga and the Ultimate Cheapskate appear on the same show in a downpour, the end of time - or at least the end of TV - is at hand.
Interesting debate here re: the pros/cons of coupons, and very reflective of what I found in my cheapskate survey for the new book (i.e. about half of the respondents swore by coupons, and the other half swore about them). In fact, in general, a main theme of the book/survey is that there's often not one "best" way to shop, live frugally, etc. --- too much depends on ones personal situation, locale, lifestyle, etc.
Stay Cheap!
