One thing I've always wondered about McDonald's is this. Are the prices the same everywhere in the country? Does a McDonald's hamburger in Grand Forks cost the same as one in San Francisco?
No... Market and location specifics can determine prices. I'm sure McD Corporate probably has price floor/ceiling limits in place, but they probably have a wide margin on those. Basically don't expect "Dollar Menu" items at a McD's on the Vegas Strip, in Times Square, or in an airport.
Edit: Here's some info for prices, both around the world and in the USA
