This is true and not often discussed. In poorer neighborhoods, the shopping options are limited and prices tend to be higher. Transportation is limited so residents can't just hop in the car and drive to the cheaper markets. I work in a very poor area and see this all the time. Even though the cheaper options are just a few miles away, they might as well be across the country for folks who have no access.

The poor are more likely to be renting and spending a larger % of income to do so, very likely to be using a laundromat, less likely to have bank accounts and thus paying for cashing checks and getting money orders, etc. Many of the money-saving tips we all share simply don't apply to the poor.
