I agree with a lot of what's been said here, but there is an element of the ridiculous with a few things:
1. The amount of repromotes: Ok, I understand that when putting together a color story, there's probably a permanent line color or two that will go perfectly and so it's used. Right now, Freckletone lipstick is repromoted in the Ungaro collection. It's permanent, and on MAC's website the description reads "full frontal neutral peach" when you click on the regular line lipsticks. When you click on Ungaro, it reads "neutral yellow-toned beige." There's no way that's an accident, and I'm sure people who aren't as makeup savvy as we are here on specktra fall for that nonsense. It's the same thing, but people think they're getting something special with a collection.
2. Replacing collection items with regular items in-store: We've all seen it many times before--the newer collection has been out for a few days, and there's something that's so pretty it sells out quickly. So MAC refills the holes in the display with a similar item that *isn't* part of the collection. I noticed this most recently when the Cult of Cherry display had Dubonnet instead of So Scarlet. There wasn't any sort of special packaging, so I'll bet a few people walked away with Dubonnet thinking it was a hot new fall color. I just think it's crappy of them to do that sort of thing, knowing that a lot of people don't obsessively follow the collections like we do, and just want something new and trendy to wear.
