@lipstick_lace_bubblegum for Nouveau Cheap
As you may know, MAC recently redesigned their website, and they're offering a (very rare) coupon code to celebrate. Now through 6/22, you can enter code MACFAN1 at checkout to receive $10 off any $50+ purchase. You must either already have an account or sign up for an account in order to use this code (registration is free; you can do it here).
IMPORTANT: If you place on order that is $100+, there will be an automatic $20 deduction off your total (no code required). I just tested that out by placing $105 worth of product in my cart and, sure enough, there was an automatic $20 deduction made to my total (I was signed in to my account when I tested this so if it doesn't work for you, make sure you're signed in first). I don't know if this discount also expires on 6/22, but I'm guessing it does.
ALSO, MAC offers free shipping on all orders, and they are now offering FREE SAMPLES with your order. When you check out, you'll see on the right side of the screen that you can choose from three different samples. That's new to me, and I think it's fantastic that they're (finally) doing this now, don't you agree?
Thanks again, @lipstickjunkieforever and @lipstick_lace_bubblegum, for the great info and tips!
