I have to admit, I bought more MAC items ever since I joined Specktra, but I know when enough is enough. I never buy backups of LE collections, because I know there'll be something better once I finish it (which takes forever). And out of all the collections that have been out this year, I've managed to buy only two items from Barbie Loves MAC and two from Slimshines. So as much as I love MAC, I don't think it's uncontrollable.
