You are best buying from a butcher instead of a big-name supermarket. A butcher is far more likely to have a more extensive range of cuts than the big-name general store, he will know the full history of his beef, will have hung it in the right way, and he will probably be happy to help you with advice on a few cooking tips.
Beef is far more prevalent in the United states than anyplace else on the planet. If you sum up the meals containing beef eaten in the whole world, you would be surprised to find that the North america is responsible for not quite 25% of it.
