Identify successful firms that offer good but not outstanding products at reasonable but not especially low prices. Do these firms disprove Porter's idea about being "stuck in the middle"?

Hint: it will be easier to think about the producers of consumer goods for this; selecting a retailer like Target or Wal-Mart is going to present unnecessary challenges in your analysis. (Also, they are using a cost-leader strategy)

2nd Hint: Cost Leader does not mean Price Leader (i.e., they might not be the least expensive option if they are able to increase margin thru higher prices and lower internal costs)

3rd Hint: If you can not think of an example, just pick a firm that you feel is "stuck in the middle" and discuss how Porter was correct with his theory.
