And at Navy and Marine bases, you can find a NEX (Navy Exchange) which is just a big department store that sells all the major brands. They even have video games and toys.
BX/base exchange for air force, PX for army. Depending in the base civilians can shop there, usually not contractors tho.
Growing up in a Navy family we had many weekend shopping trips to the Navy Exchange, mostly because it was lower priced and tax free.
