What are some good ways to control costs for groceries?
Keep a notebook. (or spreadsheet, etc. whatever works) Start to track what things cost as few can really commit this all to memory.  You'll start to find the regular sale prices and the timing of them at your supermarkets. I can't even tell you the regular price of chicken breasts, I just know the sale is $1.79-1.99/lb, and I buy enough to freeze to never pay full price.  The non-perishables are easy as you don't have to worry about spoilage. Soap you catch on sale+coupon for less than half price is worth buying to the limit, and putting in a closet.  Ex Dove soap (as the husband, I'm not about to make an issue of a brand preference. This product is good for the mrs skin in winter) - reg price $1.49. CVS had a whacky deal that offered a rebate on Dove purchase of $20, and in the end, I paid $10 for 40 bars of soap. 2 yrs worth, but 1/6 the price.  This type of strategy can raise your spending in the first month or two, but then you find you have the high runners "in stock" and as you use products from the pantry or freezer, your spending drops quite a bit. If this concept seems overwhelming, start with the top X items you buy. As stated, the one a year purchases save you far less than the things you buy weekly/monthly.
