Editor’s note

I edit the “O2” page at WaveDeals and have written about shopping deals since 2019. The codes here are supplied by O2 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 O2's seasonal sales saves the most. O2 can change its terms at any time.
