I received a coupon printout at the register from Walgreens recently, and wanted to share the information with you if you aren't already aware of it (which I wasn't!). All you need to do is spend $30.00 on beauty products, use your Balance Rewards Card, and you'll receive the printout which contains a coupon code for a free Beauty Sample Box.
Go to their web site, click the "Savings & Deals" link near the upper right corner of their home page located next to the Balance Rewards Card icon, then click the link that says "Learn More" under "Beauty Advisors + You". Follow the quick and easy instructions to enter your code and claim your prize. The current box, which I believe is the second box offered since they began this promotion last month, just became available today. I claimed mine, and it says that the offer is valid until January 25. The first box sold out quickly, so don't wait to redeem your code. You can also claim more than one box if you make multiple purchases and receive additional codes.
My understanding is that the promotion runs through February 14, and a third box will be introduced after this second box expires at the end of January.
