I'm willing to shell out that much for (ONLY) one blush for a number of reasons:
1. Blushes will last for forever and a day in my stash. I only have a couple, and I don't even use blush all that often, but I figure Moon River is unique enough to warrant purchasing.
2. I'd rather get a blush/MSF duo than a full MSF. It'll get more use from me.
3. Moon River's mono side looks a lot like a more pigmented version of Dainty, which an MA at The Bay is always trying to sell me on.
I don't really see it show up on me, though, so Moon River looks like a better choice. And it has some frost/pearl/shimmer to it, which looks good on me.
4. If I decide to pick it up at the Pro store, I could ask about getting a sample of Basic Red pigment while I'm at it. I've been lemming it for a while...(I'd love to mix a tiny bit with a dab of hair gel for red tips without actually dyeing my hair
)
...And that's all I could come up with.
