We accept significant inconvenience. Make the 45 minute bus journey or uphill bike ride there a couple times a week and overstuff a backpack. Pick up small items at the overpriced, upscale mini-marts between work and the downtown bus/train terminals, if we remember to. Rent a Zipcar or take an Uber each way to the nearest proper supermarket that's open at the conclusion of our bus rides home, and kick ourselves for the expense.
