Sometimes when you head to the store things just don’t go as planned. You’ll have a great $/$$ coupons and a shopping list that makes all your purchases under $1 and you’ll get there and something will be sold out, completely throwing off your entire plan. Instead of freaking out and buying stuff you don’t need or want and spending more money, have a plan B. List a few items you’d buy if other items are sold out, just in case your plan isn’t fool proof. And don’t forget to ask for a rain check for sold out items!
