We bought these can organizers years ago, and they have been well worth the money. The racks rotate the oldest can to the front/bottom, and they make it so easy to find what you're looking for and to know exactly how many you have. At the beginning of this new year we set some money aside for food storage, and one of the first things we did was buy enough cans to refill these racks. So now as long as I keep them full I can feel rest assured that we at least have 80 cans or so of food in our pantry in case there were an emergency. Not an entire 3-month supply, but a good start!
