Have you heard of Birchbox? It's the latest beauty products sampler-in-a-box that's been generating a whole lot of buzz — and with good reason. For $10 per month (or a one-time $110 payment for a full year), you can try out four to five larger-size high-end samples from brands such as NARS, Deborah Lippmann, Stila, Phyto, and Too Faced. There are even plenty of opportunities to earn points along with way.

Cofounder Katia Beauchamp put it best when she likened it to a mashup of fruit of the month-meets-Sephora-meets-Allure kind of experience. "My business partner Hayley Barna and I came up with the idea while we were still at school [Harvard Business School], specifically, December 2009. We had a successful beta while in school, graduated in May, and launched in September," Katia explained. Have you tried out Birchbox — or if you haven't, are you planning on it?
