Zoya.com has a sale starting tomorrow at 10 am eastern. With code “Zoya2013” you can get 3 polishes (not including the Pixie Dust line) for free, with $10 shipping. If you add $25 of additional polishes the whole thing will be $25 shipped free. 3 for $10 is the cheaper per polish route as long as you don’t want Pixie Dust; the offer is one per account, but theoretically one could have multiple accounts for multiple email addresses.
The code was live this weekend so it may be live now or early. I recommend picking out your colors sooner rather than later as colors may be on back order and delay shipment. Surely everyone can find three things they love from Zoya!
