Aldi's Super 6 rotates the cheapest fresh produce in the UK every fortnight and the Specialbuys are known to sell out in hours. We track Aldi prices across groceries, fresh, dairy, bakery, frozen and household every day so you can grab the current Super 6 before it rolls over and know which own-brand swaps genuinely beat Tesco Clubcard, Sainsbury's Nectar Prices, ASDA Rollback or Morrisons More Card. Aldi is usually cheapest on the weekly shop staples, but not always, and a few minutes here can save the price of a small lunch each week.
