Walterjn however it's one stop monthly. Compared to hitting the local grocery store every few days or week.
Some families still have to live paycheck-paycheck. So buying bulk is not something they can do, sad to say. Costs them more long run, but it's how they have to live. Only so many $$ for food in the weekly/bi-weekly budget. And joining any 'club' is out of the question for such families. 'Luxury', as they would have to see it.
Been there/done that, so I do speak from prior experiences. Many people are still doing that in 2025.
My wife worked for a doctor, wayyy back, that had a Sam's account that employees could use. We only went 1 time and could not buy anything. Would have saved a shit-ton, but not in the budget for the week.
