I found this article about Dollar Store shopping interesting. It appears that even folks with healthy incomes are now making more purchases at dollar stores as part of a new saving money mentality. Even so, our desire to purchase masses of cheap stuff continues regardless of need as these types of stores proliferate and are actually doing better than Walmart.
We have one in our neighborhood and except for some kitchenware, I have never seen anything in there I would want to spend hard-earned money on. As they are popular for groceries, I would be concerned about the origination or content of some of the products but I guess that doesn't bother most shoppers.
