If you don't know what Beauty Sage is, I suggest you give it a look. It is an online beauty shop that sells a myriad of beauty products. In addition to the products they see, they also sell sample boxes. They always have a new one for each month, and occasionally have additional available boxes. I have yet to see a "mystery" box from them, so you know what you are getting before you fork over the cash.
Here is the November Sample Box.
