Here are a couple of ideas if you are a beauty product junkie but the habit is breaking your budget.
Birchbox.com: Join the beauty sample club Birchbox by spending $10 a month to receive four or five curated beauty samples in the mail every month. When you get home from work, on your front doorstep you'll find large samples of high-end names like NARS, Stila, Kate Spade and the like. You aren't paying any shipping for the service. You can also earn points that you can spend on full-sized products.
Sephora's VIB program: The retailer's Beauty Insider program gives you a point for every dollar you spend. $100, 100 points will get you a deluxe-size sample.
BeautyFix.com: You spend $49.95 and pick 8 products a season from a list recommended to you, based on a profile you fill out on like. It works out to be about $6 a product.
LooseButton.com: This is for your friends in Canada, though they are working on expanding to the US. It's a similar service to Birchbox.
