I gave up my car 2 years ago as a trial in advance skinflintery, living in the rural home counties with a minimum 10 mile commute by bike - bloody love it, still no car. Less tendency to pop into shops to buy stuff I didn't know I wanted, too. Like Waitrose sarnies!
I've just bought a Waitrose 1 sandwich.
You can keep your Tesco Value lifestyle, I'm all in for the artisan bread and balsamic something something. Nom nom nom.
