I just purchased several more colors of Zoya nail polish. I was over on the E-Polish Blog and noticed a post with a new Zoya code. I completely missed it on the Zoya blog I subscribed to, but it wouldn't be the first time!
Go to the Unofficial Polish Poll and vote for your favorite, you will receive your code on the next screen. Put $20 worth of Zoya product into your cart and then put in $18 worth of additional products. The code will take the $18 off your total. Shipping is $6.95.
Check out some great polish photography over at The Polish Addict. I wish I had those camera skills!
