MAC Canada site you can get this for free, enter the code "MACSAMPLE" until Nov 14, 2010. I was back and forth about this blush, and frankly I am happy to have it, but it's totally not "necessary". It's possibly the most true peach that MAC has ever released, lots of the peach blushes that I have can be slightly darker or have pink or coral undertones, this one is just peach. It's a satin finish, I find it a bit chalky and you have definitely have to pack it to get the right colour payoff. It's very light, and even on me, I am quite fair this takes some work.
All in all, it's a nice blush to have, but to have Peaches, Utterly Game AND My Highland Honey is not necessary and suspect that applied on the cheeks no one (but you) can tell the difference.
Did you pick up My Highland Honey or other items from the new MAC collection?
