What are some good ways to control costs for groceries?
For a while I tried shopping multiple grocery stores, checking fliers each week from three different stores and then making the trip to all three stores to save ten cents on each item. After a couple months, I decided it just wasn't worth it.  So, I picked my favorite store.  I shop once a week, after reviewing the flier and making a list.  I clip coupons and try to only buy what's on my list.  (I confess that coupons sometimes get me to buy a brand or item I wouldn't have otherwise... it's my weakness!) The biggest place that we save money though, is by paying attention to meat prices.  I know that chicken and pork go on sale for $1.99/lb every 4 to 6 weeks at my grocery store.  When it does, I buy a enough to last until the next sale, and freeze it in single-meal portions.  Steak and fish are special treats, but on the rare occasion that they're less than $4/lb, I'll buy those.  We also try to limit our meat consumption to every-other-day. It's not worth it for me to obsess over the price of ketchup that I buy twice a year, but on expensive items like meat, and items we use daily, I become familiar with their regular prices and sale prices, and buy extra when it's on sale.  If, like me, you don't have room in your brain to keep track of the prices of everything, stick with the things you spend the most on, either because they're expensive, or you buy a lot.
