Yo, here's my chat yesterday... was wondering about the B2M and depotted shadows:
Welcome to MAC Cosmetics Online. One of our Artists will be with you shortly.
Hello. Thank you for your interest in MAC Cosmetics. My name is Sara. How may I assist you?
Evey: Hi, I have a question about back 2 mac
Evey: If I have removed the eyeshadow pans from the plastic containers, are they still elidgable for return for back 2 mac?
Sara: Hi Evey! If it is a Pro Palette refill (it will have a magnet and sticker on the bottom), you can use it towards Back to MAC. If it's a shadow from regular packaging that you "depotted", you cannot use both the plastic container and the refill.
Evey: Okay, thank you!
Sara: No problem! Save all of your Pro Palette refills for recycling!
