Editor’s note

I edit the “M&M's” page at WaveDeals and have written about gifts deals since 2019. The codes here are supplied by M&M's 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 M&M's's seasonal sales saves the most. M&M's can change its terms at any time.
