Tip # 11 Rainchecks!
My mom used to get these all of the time when I was growing up. I somehow forgot that they even existed until about a year ago. The next time you go to the grocery store and they are out of what you had planned to buy, simply swing by customer service on your way out and pick up a raincheck! It only takes a few extra minutes. The best part? Sometimes a coupon shows up while you are waiting for them to restock the product you have a raincheck for!!
