The first sale is from HauteLook which has some pretty awesome sets and tools from Orly. Full sized polishes are as low as $4.50 each, including Stone Cold which I reviewed here. This sale ends Ends Monday, January 7, 2013 at 8AM Pacific.
The second sale is a pretty amazing sale from Sally Beauty: BOGO FREE for any product up to $10.99 value. This sale ends Ends Thursday, January 31, 2013. This includes polishes, tools and nail therapy products. This is available both in-store and online, just use code 444634 at checkout online.
I've had only good experiences using Orly products and recommend them especially with these amazing sales going on.
Have you tried Orly? What are some products from their line that you would recommend?
