Well I live in SF (and have done for last 7 years)... you can buy toothpaste for <2$ at CVS/Walgreens no problem (feel free to check their websites).
Groceries is all over the place, no different to shopping in the UK. I can buy cheap cuts of meat, and lots of veggies for very little or I can drop $100+ on Wagyu. Honestly, everything in SF is def. cheaper than London EXCEPT housing. Which will beggar you.
I'll take that as "I don't have a fucking clue but I'm going to comment on it anyway", because I don't remember you coming to NY or Boulder with me.
