In the history of my MAC collection I've only backed up two items. Feline Khol pencil. Wish I knew back then the rate that they repromote this one item because I wouldnt have done that. The other was Boy Bait Creamsheen glass its the perfect nude for my perfect nude lip. Little did I know they were making that one perm. A few days ago I took the back up plunge yet again. I had to grab another Sassy Grass. This color is too pretty and too unique to my collection. I'm sure they will eventually repromote it again. However by then I'm going to be in need of another one. I never thought I would get so much use out of a color like this. When I went to my freestanding store and saw they got more in (it was sold out previously) I had to grab it.
