5 ways to save more money at dollar stores

While other U.S. retail stores are disappearing, dollar stores are popping up everywhere. In fact, the two biggest operators added 942 storefronts over a recent 12-month stretch, for a total

of more than 31,000 sites. That's more than all the McDonald's and Starbucks outlets in the U.S. combined. That's no surprise to anyone who has shopped in a dollar store

lately. These retailers — Dollar Tree and Family Dollar (both owned by the same company), plus Dollar General — now carry all kinds of groceries, including brand-name products, in addition

to usual dollar store fare like no-name batteries and greeting cards. A new study by the University of Nevada, Las Vegas, found that 84 percent of produce and 89.5 percent of non-produce

items cost much less at these discount chains, and the produce quality is comparable to what's in supermarkets. But just because there are lots of bargains doesn't mean

everything's a good deal. Here are five ways to save more at dollar stores — and avoid the duds. 1. READ THE INGREDIENTS When buying packaged foods like granola bars, crackers, soup and

cereal from unknown brands, check nutrition labels. I found a box of granola bars that looked a lot like a Quaker Oats product. But the top ingredient in the dollar store product was high

fructose corn syrup; Quaker Oats lists granola first. 2. DO THE MATH Sizes are often different at dollar stores, so it's not always easy to do a quick apples-to-apples price comparison.

My advice: Before going, jot down unit prices of items you buy regularly at your grocery store. Then, if need be, use the calculator on your smartphone to compare those to dollar store

prices. Some products aren't as cheap as they might seem. For example, I bought a 5-ounce can of shaving cream at Dollar Tree for $1, which comes out to 20 cents per ounce. Bed Bath

& Beyond, though, sold a 10-ounce container of the same brand of shaving cream for $1.24, or 12.4 cents an ounce — 38 percent less. FOR WAYS TO SAVE AND MORE, GET AARP’S MONTHLY MONEY

NEWSLETTER. 3. PILE ON THE COUPONS Dollar General and Family Dollar feature sales and juicy store coupons on their websites, plus they accept manufacturer coupons. You can also download

dollar store phone apps for coupons on the go. The Family Dollar app's newly launched Smart Spins feature offers surprise coupons, and the store allows you to combine store and

manufacturer coupons. Just be sure to check retailer websites for restrictions; for example, Dollar Tree — where everything truly costs no more than a dollar — accepts manufacturer coupons,

but you're limited to four a day. Also sign up for email alerts to keep up on special deals.
