Hey!!!!

Ok I have a question! I thought MAC eyeshadows could only be bought with the flip top because that is the only way I've ever seen them besides the palettes. I was on ebay.com the other day looking at Wishful from the Ornamentalism collection and they had the flip top and screw top. I've never seen the screw top so i thought it was fake or something!!! Could someone please clarify this for me and let me know the different ways they sell the eyeshadows! Just the other day i found out you can buy the eyeshadow by the pan only instead of the flip-top and I heard it's a few bucks cheaper? Is this true?
