Sale: Sally Beauty ORLY Polish - Buy One Get One Free
I grabbed a basket because I love this polish.
The regular colors are $6.99 a bottle ($6.49 if you're a beauty club card member). So you'll get two bottles for $7. Great deal for decent polish.
You can get this deal online, too. Use code "444239" at checkout, but the web site only seems to honor one free bottle. And the shipping cost is $5.95. So I'd head out to your local store for this deal to save a few dollars.
You might want to grab one of their flyers, or print out that page (here's a link to the flyer) since it says "with coupon". Just in case :)
