I just got off live chat, asking about the Dazzleglasses:
Welcome to MAC Cosmetics Online. Your personal Makeup Artist will be with you shortly.
Hello. Thank you for your interest in MAC Cosmetics. My name is Stacey. How may I assist you?
Okami: I have a question about the Double Dazzle collection that's set to be released April 30th.
Okami: Are the Dazzleglasses in that collection going to be permanent products, or limited edition?
Stacey: Hi Okami! Let me take a peek....
Okami: Thanks!
Stacey: Sorry for the delay!
Okami: No problem!
Stacey: Most are going to be permanent. There are a few that will be limited.
Okami: Can you tell me which ones are limited? I'm planning a trip to pick some up and since I can't buy all of them right away (I wish!) I'd like to be sure to get the limited edition ones right away.
Stacey: Sure!
Stacey: Goldyrocks, Utterly Posh and Stop! Look! are the ones that are limited.
Okami: Those are the only limited ones?
Stacey: They are.
Okami: Great!! I was worried that more than just three would be limited. Thank you so very much!
Stacey: You're welcome Okami!
Okami: Have a great day!
So apparently only these three are going to be LE. It sucks that any of them are, but at least it's only three, right?
