America's Cheapest Family Gets You Right on the Money by Annette Economides, Steve Economides (2007, Paperback)

For those people drowning in credit card debt (and there are MANY out there), this is THE book for them. It details many tips on saving money on groceries, utilities, vehicles, etc., but one alone is worth the cover price: carry no debt except for your house mortgage (which you will pay off as quickly as you can). I don't know about paying off your house (a wonderful achievement!), but cutting up the credit cards and paying hard-earned and hard-saved cash for absolutely everything else, including your vehicles, is excellent advice. Very worthy reading!
