Right now, several Real Techniques brushes are 25% off on Amazon HERE, and you get free shipping on orders of $35+ if you are not Prime (free if you're Prime, of course). Take a moment to look through all three pages, since some items are not on sale, some don't qualify for free shipping, and others do. I do not know how long this sale will last, so don't wait (if you're interested).
The Bold Metals collection is exclusive to Ulta, so if that's what you were looking for, be sure check out the Ulta deal I posted about HERE.
Thanks again, Nicole, for the great tip!
