Most of them are, yes.
The scents they're pushing are the ones that the management is trying to push, due to advertising deals or other kinds of corporate arrangements.
Unfortunately, that's what you're going to get in Department Stores: mostly ignorant people pushing what they're told to push (and told to push HARD, too), combined with part time employees that usually couldn't care less about you, not to mention what you wear or are looking for
However, I've found Nordstrom's to be the opposite, at least here in St Louis. I LOVE my Nordie's and LOVE their SAs that work in their fragrance departments. They are truly amazing. If you have a chance to go to one, do so. They will impress you.
