I edit the “El CidUS” page at WaveDeals and have written about travel deals since 2016. The codes here are supplied by El CidUS 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 El CidUS's seasonal sales saves the most. El CidUS can change its terms at any time.
