I've got another recommendation for Saks: Corina Andrade at the Bond No. 9 counter. She's great! She hooks you up with samples, will call during bonus points events, etc. Here's her email: firstname.lastname@example.org.
At NM, I work with Janelle at the Laura Mercier Counter.
I also have worked with a couple of SAs at NM Walnut Creek. I don't have their info at the moment, but can look it up if you're interested.
