Loyalty card
What it really means
Free membership cards from shops (Tesco Clubcard, Nectar, Boots Advantage, coffee shop stamp cards) that give member prices or points. Worth getting for any shop you use often — they are all free.
Context, tips & common mistakes
UK supermarket loyalty schemes have shifted from collecting points to two-tier pricing: shelves show a member price and a higher non-member price on thousands of items, which makes the free sign-up effectively mandatory economics — over a year the gap is serious money. Sign up online or in the app in minutes, and the app's digital card scans at any till.
The small print of daily life: forgot your card and the app is dead? Some tills can look you up or apply a store card — asking costs nothing. Points still exist and quietly accumulate into vouchers, which several schemes let you multiply by spending with partner businesses. The trade you are making is data — your shopping history personalises offers and marketing — which most people accept and privacy-minded people should at least make knowingly.
