Many thanks to reader Tiffany on Facebook for this one!
On the Walgreens site now: BOGOFREE all Real Techniques single brushes HERE and BOGOFREE all EcoTools single brushes HERE. Free shipping on orders $35+. If you're doing additional hauling on the Wags site today, you can use code 25CYBER for 25% off all NON-SALE items (does not apply to the Real Techniques or EcoTools deals). But this code DOES include brands like LA Girl, Black Radiance, e.l.f. (including Disney), Milani, and much more. Remember that Walgreens also sells higher-end brands on their site that you can use this code with (Bellapierre, Bourjois, etc.) so check the drop-down list HERE for all brands. This also applies to skincare HERE and everything else in the beauty department (as long as it's not already on sale).
Thanks again for the great tip, Tiffany!
