Buying diapers is costly. So much money goes into such a short-term item that's just going to go into the trash, sometimes moments after you buy them. Luckily there's a way to get something back. Alecia tells us a great way to get a free toy for your child simply by buying diapers. Many companies have rewards programs; Alecia's favorite is Pampers, but it's just one of the free giveaways available to you and your family.
