I buy meat from a proper butcher in the next town, the one in mine is a hiked price rip off deli type affair. Our local greengrocer ran off when Tesco tried to build their ill fated store, so for two years no veggies, fruit or Tesco.
I buy cleaning supplies from the pound shop (if it was what I would get in the supermarket anyway.) Tinned tomatoes,basic flour, Lidls own clothes washing liquid if I can't get to Costco : where I buy branded ; dishwasher stuff, soap powder cubes, loo rolls, kitchen rolls, Pukka pies, and batteries. I try to keep my eyes closed to the other aisles. Nearly died a death when local ironmonger wanted seventy quid for a wheelie bin, so they came from Costco too at 25 quid each. Drinks for kids school lunches come from there too.
I would only buy Kellogs Cornflakes and Fairy washing up liquid, although copies have gotten better in recent years, just not the same - imho - but if I was on my uppers I would still try to stretch to these two things only.
