KNOXVILLE, Tenn — Take full advantage of the statewide grocery sales tax holiday happening this month by freezing your food. There are many reasons to consider freezing, according to the website Thrifty Frugal Mom. Freezing already prepared food makes it easy to grab for a meal or snack later. Especially when you buy in bulk and stock up during sales. You won’t have to worry about having to toss stale or spoiled food. If you freeze fresh fruits and veggies when they are in season or on sale you can enjoy them all year long.
