Try the Live Chat on the MAC website and ask them. Now that they're selling those pallets, I wonder if they're going to start selling the eyeshadow/blush refills?
I think I might email them, I want a few eyeshadows but would rather buy them in the pan form so I don't have to depot them. Knowing my luck I'd buy them and the pro pans would appear on the website.
I think I might die of happiness if they do start selling them... I know you can order them from the pro line... but I'm lazy and I can never be bothered
