Sephora.com is giving VIB members 15% off from March 29th through April 6th with code CHICWEEK, which can be used as often as you’d like. For regular Beauty Insiders, from March 30th through April 5th, get 15% off with code CHICBI. Happy shopping!
As far as I know, this is for U.S. only. It may extend in-store for Canadians, as it specifically lists in the fine print that it excludes Canadian checkout at sephora.com.
