I found: https://www.sachacosmetics.com/
Pretty cool site for makeup artists. I bought the MAC Pro Makeup Palette to fit in 15 eyeshadows or blushes.
EDIT: To depot eyeshadows so you can place them in th pallette, see this visual tutorial on how to do it, CLICK HERE
Also, a lot of people seem to have trouble finding Milani Cosmetics (they have awesome eyeshadows), try CVS Pharmacy or order them online here: http://www.bestbeautyonline.com/milani.asp.
CVS had a Milani Eyeshadow Sale, where they were ALL 50% off, so I bought Antique Gold, Atlantis, and Shock. Of course I will soon be depotting these so that they can fit in my MAC makeup palette!
I have another tutorial coming up as well!
