I logged into Sephora.com today to see if I could get the NAKED palette, and I saw this gem:
AmorePacific 500 point perk that has been up since last month. Hehe. Cute mistake.
I think it's safe to assume that the next 500 point perk is the Benefit set pictured.
Don't worry B.E. ladies, the Diamond Buxom Babes set is still available online for now, but I think Sephora may be updating their website tonight or tomorrow. So it's there tonight, but no guarantees if it will be there tomorrow.
