I don't know how true this will be other places, but apparently Macy's told the MAC MUAs that they can only do Macy's card orders over the phone for this collection.
When I was there, they had to turn down some poor frantic person on the phone. They also had a security guy hanging around just in case. Crazy.
Mine did not have a line, and if you got there at 10 (opening), you could get multiples of the whole collection if you wanted to. Unfortunately, they also did not have testers, so I couldn't swatch anything to make sure I liked it. I went ahead and bought MMB because I had Plenti points to use (so $ off) and because I want that one and don't want to gamble on the one in the mail. That means I will have an extra available for someone on here, or I will just return it unopened. I did check out the liptensity lippies, though.
