Editor's note
I edit the “Insulation Superstore” page at WaveDeals and have written about shopping deals since 2016. The codes here are supplied by Insulation Superstore through its affiliate program and updated automatically; I read the terms, flag exclusions where the retailer states them, and take down codes that shoppers vote as broken. From what I see, stacking a working code with Insulation Superstore's seasonal sales saves the most. Insulation Superstore can change its terms at any time.
