Walmart.com has the Rubbermaid 24-Piece Food Storage Set with Easy-Find Lids for $10.00. Free Shipping when you use Site-to-Store.
What do I love about this product? I love that the containers and lids stack together so that it is always easy to find them. I love that this is a reusable product and discourages the use of disposable products such as plastic bags. And according to the Rubbermaid website these containers are BPA-free, which means they are safer for you and your children.
