You’re paying more these days not only at the gas pump but also at the grocery store. Blame it on rising oil prices, disappointing crop yields, global warming, or the weak dollar. What it all means is that you need to find smart ways to save. These expert tips and strategies can help you slash your grocery costs without sacrificing nutrition.

1. Plan Ahead Katherine Tallmadge, RD, says, "Take inventory of what you have on hand so you don’t overbuy. Create a detailed shopping list based on your needs and weekly menu plan, and take into account how you plan on using leftovers." Have a light snack before you go shopping, and stick to your grocery list to help avoid impulse purchases or costly mistakes like falling for the displays at the end of the aisles. Before you plan your weekly menu, check the ads to see what’s on sale and use coupons to take advantage of sales and money-saving coupons. You can even sign up online to receive coupons and email alerts from your favorite grocers.
