Although your grocery bill may be one of your biggest household expenses each month, it's also one of the easiest to trim down. That's because it contains so many variables.

Before you adjust what you buy, think about when you buy. Try going to the supermarket when your partner (or someone else) can watch your baby. Being less distracted and having more time, you'll find it easier to comparison shop and limit hasty purchases or impulse buys. And don't shop when you're hungry!

It's also helpful to look at how you buy. Always remember your discount card (if your store offers one) and a specific shopping list. Keep a running list of foods your family consumes on a routine basis – there are great apps to help you do this – and stock up when the price is low. Coupons can help cut costs, too.

Consider changing what you buy. One option is to buy foods in bulk if you consume them often and have storage space. Try alternatives to meat on occasion, since they generally cost less. Limit premade meals and other convenience foods – cooking from scratch doesn't necessarily have to consume a lot of time. Making a menu of meals for the week helps save money, too, because you won't buy food you don't use and end up tossing.  For ideas on easy-to-make family meals, check out our Recipe Finder.

Finally, look at where you buy. Is the local grocery the store with the lowest prices or merely the most convenient place? Warehouse stores usually offer better deals on nonperishable items, and a local farmer's market may have better buys on seasonal produce.
