This review focuses more on the MAC counter in-store than anything (though Macy's itself is wonderful and protip: They have plus sized tights in every shade imaginable).
I've been in here quite a few times for various MAC purchases. It's easy to find crappy reviews of MAC counters online- in fact, I saw one today, which is what prompted me to give this one a thumbs-up. If they don't have it, they'll order it in. If you'd like your skin matched for foundation, they will help you. They aren't pushy, either.
I do wish they had the more limited edition stuff (like Ablaze. Oh Ablaze, wherefore art thou Ablaze?), but this store has good service, and if you're looking for a MAC counter where you will have a positive experience, this is it.
