Best price found on this 5-window kit!

I had heard about the energy-saving wonders of these shrink film kits, but had never tried one — until this past winter. Our windows are pretty old and have lost some of their insulating capacity over time. But, we definitely noticed a difference after applying this window kit to our windows — it seems to have stopped the cold air coming in from around the edges. Coupled with our Nest thermostat, we were able to save a bundle on winter energy costs!

This kit is available for $4.17 at Amazon as an add-on item, and would be a great item to stock up on for next year. Free shipping for Prime members or with orders of $25 or more.
