Walmart is offering the Snapware 20 piece Airtight Plastic Food Storage Set for only $12.00. This set normally sells for $19.97, so this is a nice savings. You can have this shipped to your house for $0.97 or have it shipped to your store for free.
These are great containers and do seal very tightly. One of my friends has a set of these container and several times she has given me things in them and I liked the container so well I wondered if she would miss it if I forgot to give it back:). Maybe I should just buy my own set today.
