Well, maybe, except that living in London, I've found I can queue for an hour to get in to the local supermarket, or I can pop in to the big Turkish cornerstore, where they've installed a butcher's counter at the back (with an actual butcher, a guy with a big blade hacking up carcasses) and have the freshest veg straight from New Spitalfields veg market (huge bunches of mint, parsley and coriander for 50p each, tomatoes that taste of tomato instead of red mush, baby cucumbers, best peaches I've had in ages, etc). There's homemade baklava and borek and fresh flatbreads...
We've actually started eating much more tasty home-made food now I don't spend ~2hrs a day schlepping in to the city each day. I could get used to this.
