Have you ever heard of Zoya Nail polish?
They are high quality, chemical free (therefore great for kids and pregnant ladies), salon nail polishes with TONS of colors to choose from.
Here is the great part - until Friday Zoya is giving away 3 free nail polishes to anyone who likes them on facebook. You do have to pay shipping of $6.95 but since each polish usually costs around $7 you can consider this a buy one get two free sale! Head over here and "like" them then pick out your 3 colors on their website (good luck with that!) Lastly use the code FB2011 at checkout to get the discount.
I highly recommend this nail polish and am looking for to getting my three colors in the mail!
