Don't worry...if you're not hip, neither was I until last week. I was perusing through my YouTube subscriptions (because I love to watch makeup tutorials, hauls, and reviews) and came upon a video by AdoreDior0x titled, My First Birchbox!! February 2011 (view the video and Birchbox Website) for more details.
For just $10/month or $110/year, Birchbox will deliver 4-5 deluxe samples to you from your favorite brands each month. Each month you will receive something different. Some of the brands are NARS, benefit, Korres, Kiehl's, Laura Mercier, Stila, and bareMinerals. For someone like me who has always wanted to try products from these brands but hasn't had the $$ to pay full price for an item, I thought this was ideal! You're basically getting a sample from a luxury brand for only $2/month. If you like it, you can purchase the product from their site; if not, you lost $10 at the most/month which isn't bad at all.
Visit their site and view the video if you want to learn more about Birchbox and what it has to offer. There are no hidden fees and you can cancel your subscription at any time. Also, they have a 90 day return policy on full-size product purchases. Last, but certainly not least, if you review one of the products you received a sample for, you receive loyalty points which can go towards purchasing a full-size product.
