A coupon pro reveals the best strategies for stretching your grocery money
Sometimes buying in smaller packages can actually save you more. For example, let's say you have a $1.50 coupon for laundry detergent. If you buy the 200-oz. bottle for $7.49, you pay $5.99, or 3 cents per ounce. If you buy the 100-oz. bottle for $3.99, you pay $2.49, or 2.5 cents per ounce. The smaller bottle is a better value. Collect two coupons and buy two small bottles, and you save even more.
