Overview
- Which?'s March 2026 daily scan of 241 branded items found Asda's basket cost £813.16.
- That total was 1% lower than Tesco's Clubcard basket and 4% below Sainsbury's Nectar basket.
- Non‑members faced higher bills, with Tesco at £911.64 and Sainsbury's at £933.82 against Asda's £813.16, and both were pricier than Waitrose at £902.83.
- Some items showed extreme gaps, including Nescafé Azera at £3.50 with a Clubcard versus £7.25 without, and Tilda boil‑in‑the‑bag rice at £1 in Tesco without a card versus £2.25 in Waitrose.
- The study looked only at branded goods, leaving out Aldi and Lidl, and retailers said their loyalty deals and other offers still give value.
