Nectar is the loyalty programme used by Sainsbury's, the British supermarket chain, where shoppers collect points at the till by scanning a card or app. The familiar scanner chime has become part of the weekly shop routine for UK customers, which is why short recordings of it circulate online as a recognisable meme sound. Creators reach for it whenever a video needs an instant 'British supermarket' cue, from shopping parodies to haul videos, because almost every local viewer places the beep immediately.
