Pretty much the best way I've found to save money is to never go shopping. But, sometimes, in the course of life, there's things you need, particularly in the way of food. So every now and then I think I should learn how to be a good bargain shopper. When I'm in that mood, I invariably find myself reading books like Jamie Chase's The Lazy Couponer: How to Save $25,000 Per Year in Just 45 Minutes Per Week with No Stockpiling, No Item Tracking, and No Sales Chasing!.
It's an interesting book, and it's got a lot going for it. Chase does not advocate chasing sales or stockpiling supplies, or other super-couponer strategies like that, which is a relief. But it turns out that what she does advocate--doubling up store and manufacturers' coupons (they're called Qs, by the way; Chase's entire first chapter lays out all the couponing jargo for you), printing off coupons right before you go shopping, and stacking coupons with purchases designed to earn you store rewards like CVS's "Extra Care Bucks"--well, it's still too much work for me.
I'm going to stick with just never shopping, but if you'd like a good low-key guide to using coupons at grocery stores, drugstores, and online, do consider this one.
