I used to but not as much now. Coffee was always a big one for me but we get that from Aldi now and it’s perfectly good 😊
Cereal was another but I try to not eat as much anymore. Muesli had to be Alpen but then I started mixing my own and it was superb!
Same with soft drinks, thought all the cheaper versions were gross! I still do to be fair, but again it’s something I cut out massively.

Yes I used to only drink coke and it had to be branded but now I don’t drink it really.
