Meat, kitchen roll (Bounty), toilet roll (Andrex or Charmin), cereal (I love Just Right...it's that or nothing, so I buy loads of it when it's on offer, like now! and Rice Krispies for junior).
I'll buy cheap coffee (Sainsbury's own is actually quite good for instant; real coffee I treat myself to when it's on offer); cheap clingfilm (stores own) and fruit and veg. Aldi's 6 for 39p is usually good. Their clems last week were divine.
Thanks for this thread. It's quite fascinating looking at other people's habits and it reminded me of a few of my own which I'd forgotten about.
