My impulse buying is seriously MAC's fault. They really introduce too many collections within a short period of time. I do want barbie though. At first i didn't want the doll, but the more I stare at her, I just have to get her. As far as the makeup, from day one I wanted most of the eyeshadows, a blush, and a lipstick or two. now I feel like I need everything. I change my list everyday. At first I thought I do buy because thats what others are buying, but I know when the collection is released next week I'll only get what i really wanted. Not what others are buying... just to say I have it. I do have a bad addiction though, and MAC is only making it worse. Last year at this time the only Mac thing I owned was a lipglass and a perfume. What I have now is just pure insane.
