Editor’s note

Hi — I look after the “Butter LONDON” page here at WaveDeals. Since 2016 I've published and maintained gifts deals, verifying coupon terms and exclusions before anything goes live and updating quickly when things move. In practice, the deepest savings at Butter LONDON appear during sale events and via sitewide codes at checkout. Please double-check the offer details, as Butter LONDON can adjust terms and some codes only apply in certain regions.
