I know the NYX Rocker Chic Palettes have received mixed reviews but if you've been wanting one, I don't know if the price will get any lower than it is right now at Ulta.
As you can see above, these palettes are currently 50% off HERE. Use code 309300 online or show this coupon in-store to receive 20% off a single item (I'm actually not sure if these are available in-store; maybe one of you can confirm?). That brings your price down from $8.99 to $7.19 for one palette (original retail price: $17.99).
OR: if you're ordering online and you want two of these palettes, use code 205730 for $5 off your $15+ order. That would bring the price down from $17.98 to $12.98 for two palettes, or $6.49 each (original retail price for 2 palettes: $35.98).
Hope that helps!
