Beauty Insiders and VIBs should have received their $20 or $15 gift cards respectively. If you haven't, make sure you keep an eye out for them! They require a $40 minimum purchase and are good until December 13.
This is going to help me out a ton as I just needed to buy new face wash which costs me an arm and a leg.
Here is a really useful link I found that shows how you can maximize your gift card and possibly not spend any money (in the end).
