Day 9: Watch out when you’re buying in bulk
Buying in small packages sometimes saves you more, especially if you have a coupon. Suppose you have a $1.50 coupon for laundry detergent. If you buy a 200-oz. bottle for $7.49 and use the coupon, that would be 3 cents per ounce. But a 100-oz. bottle for $3.99 would be 2.5 cents per ounce with the coupon. Even better: clip two coupons and buy two small bottles.
