Right now, Amazon is offering a great deal on the Rubbermaid Blox for only $5.99 ( a $13.99 Value). Also, they have several other styles and lunchboxes for a little bit more!
These work great with any lunch box to keep your lunches cold. Actually, I use them in my kiddos packit to save on using ziploc bags. I was going to grab another set at Kroger but they were not on sale.
This will ship for Free with Super Saver Shipping with orders of $35 or more. You can upgrade your membership to Amazon Prime and get Free 2-Day Shipping.
