What state have the best discount?
Answers: Depends on what economic facts you want to look at. I'll assume unemployment rate is a polite proxy for what you have in mind:
The Western states excluding the coast enjoy the lowest unemployment rates (the Dakotas, Idaho, Nebraska, Oklahoma, Wyoming, Utah...)
The states with the superlative unemployment rate right now are Michigan, Alaska, D.C., California, and Rhode Island.
