I lived in Boston for a while (with a car, but putting low miles on it)
Curious, did buying groceries more end up costing more?
When I switched from buying in bulk periodically to buying small more often, I can say that my first few weeks definitely cost more. I had a mindset about buying for X weeks out instead of X days out that took a bit to shake. In the process I realized how much food waste I was having by purchasing in bulk and not fully using everything, and I naturally switched to purchasing less at the grocery store. Both because it meant carrying less home but also because it was cheaper. Now I buy more or less exactly what I need and I can say on average my grocery spending is less now (avg monthly) than it was when I was buying in bulk.
