This has probably been done before but supermarkets sometimes change prices and recipes so quality can change...
What are your best budget/value food purchases (as in the tesco value, sainsburys basics etc...). I think I saw someone mention that Sainsburys Basics tea bags were very good?
I'm in a city so have all supermarkets available to me (I think!) but what should I be buying from where? I normally shop at Tescos with the occasional Waitrose or Lidle shop chucked in depending on how flush/bored I am
