I will not skimp on toilet paper. cheap toilet paper is rubbish.
Also see crap washing up liquid (Not that I use it)
Wine
Everyday drinking wine £10-12 a bottle, for special occasions £30-60 a bottle. More than that isn't needed unless you don't know what you're doing. Less than that and you clearly don't appreciate good wine. NTTAWWI
Life's too short to drink bad wine, as they say.
