Skin Care Rx is offering their Beauty Cache free with any $100 in purchases. The Beauty Cache is a kit of beauty samples in a case, and is a great way to sample a wide variety of products. The last time I got one, I was rather impressed with amount of high quality items in it.
To get your free Beauty Cache, add one to your cart, and use the Skin Care Rx coupon code BEAUTYCACHE. The promotion runs through May 15, 2011 and quantities are limited. So if you want one, you might want to shop sooner than later!
