I think save. There are lots of inexpensive blushes that are pretty colors and I've never had one that fades or looks like poo. I have Cover Girl, Maybelline, Physicans Formula, Loreal, and also never had to use a lot to make it show up. I also have Orgasm, and it's ok. It's pretty, but it's not a big difference from many shades I already have.
I would only splurge if I need a color I can't find in drugstores.
