I’m over 20 miles away from the nearest Farmfoods but the prices in Home Bargains and Savers are much lower than the supermarkets. My DS saw Child’s Farm infant hair and body wash for a fraction of the Waitrise “offer” price! I get Simple shampoo and Arm & Hammer toothpaste (British made) in HB, though my favourite moisturiser is from Aldi. HB are much better for many food items too: milled flax/linseeds, chia seeds, crystallised ginger, chocolate chips, Graham’s (Scottish) butter, big free range eggs (from Ireland, though I do buy locally when they’re at the gate).
The Trolley app is worth having to compare prices, if you’ve time to visit different stores.
