It's been discontinued since last year, I think.
I'm like you, I'm sooooo sad...
and was wondering how come no one else was talking about it at all when it disappeared from the site.
Have you seen or tried the powder blush called "Apricot Totty" by POUT?
It looks similar to Foolish Me, but when it's applied it's a little lighter, but if you have tanned skin, I imagine it would look pretty on you.
