This week, 3/9-3/15 at Ulta, Eco Tools and Real Techniques are buy one get one 50%, but you can mix and match brands so you can grab one from Eco Tools and get the other from Real Techniques for 50% off, and vise versa.
I use Real Techniques Buffing Brush every day to apply my foundation and their Expert Face Brush to apply cream contour. Both are amazing quality brushes. I also use the Eco Tools Flat Eyeliner Brush to apply eye shadow to my lower lash line, and if you couldn't get your hands on the NARS Ita Brush, a possible dupe for this could be the Eco Tools Face and Body Sculpting Brush!
And to make this deal even better, you can stack this sale with Ulta's $3.50 off $10 coupon!
