Dollar General

What is it with the Dollar General? They are like the rabbit of the discount retailer — I mean seriously, they are everywhere. I could probably walk to half a dozen of them in a few minutes. If I walked, I mean.
The stores themselves are a lot better than they used to be, when they were like a small store crammed with anything — maybe even everything — that no one used to want. Now they are about the same, but the lighting is better and they seem to have hired a merchandiser or Martha Stewart or something.
I have to say that I really have trouble figuring out the stores. It is not that I have a problem with discounts, as I find myself shopping in the Wal Mart. Or even the Dollar Tree. But I do not get the Dollar General. They are like the credit fixing version of the Wal Mart — you want to think you are getting something decent but if you take the time to compare what you get, it is so overpriced just because you think you are getting a deal it is totally not worth it.
