Editor’s note

Hi — I look after the “Diet Chef” page here at WaveDeals. I've covered food & drink promotions since 2018. The list above is refreshed daily from Diet Chef's affiliate program; when a code is reported as not working I check it against the retailer's terms. The deepest savings at Diet Chef tend to appear during sale events and via sitewide codes. Please double-check the offer details, as Diet Chef can adjust terms and some codes only apply in certain regions.
