If you save 8 (I believe its still 8) MAC containers (eyeshadow containers, lipstick tubes, eyelash cases), you can bring them to any MAC counter and turn it in for a free lipstick! Its the RECYCLING program. If you go to a MAC store, I believe you can trade it in for a lipstick, lipgloss, or eyeshadow. Good way to save $14 bucks or so!
AND if you didn't already know, MAC has these palettes that you can buy and start buying the palette eyeshadows for. The palette eyeshadows are 4 bucks cheaper than the regular ones... which can really add up if you buy a lot like me. The palette is about $15, and it holds 15 different eyeshadows. So with 15 eyeshadows, you're saving 60 bucks minus 15 bucks for the palette, so you'll save $45 bucks after your palette is filled! Cool, huh?
Also... you can transer your eyeshadows in those regular containers into your palettes... and then recycle those containers for your freebie.
I thought I'd tell that to the MAC lovers who didn't already know. (You'd be surprised by how many people who didn't know this!)
Stay beautiful!
