you don't tend to arbitrage for lower prices Are you kidding? I grew up relatively poor, and we watched for sales all the time -- one needs to more aggressively pursue sales / lower prices, as long as the savings exceed the travel cost / value of time. Perhaps you meant that the poor won't have the same ability to stock up on sale items because they can't front the cash, but that's different from saying they don't pursue the lowest price available for everyday needs. Besides, Grocery Outlet gets some cool things that the top-tier stores don't even carry. ;)
