This post is particularly relevant because right now these polishes can be found at Nordstrom Rack for $4.99, which is where I grabbed mine. It is also on sale for $5 at Urban Decay's website (it's supposedly normally $15). Nordstrom Rack had blue, purple, green, and a graphite color. The website has a green (Zodiac), orangey red (Bang), and blue (Chaos). The colors are supposed to be limited edition each season.
The packaging was very cute. The box made it seem very classy, and as you can see there is a skull on the top.
I ended up selling this polish because I have soooooo many that are very similar to this color. However, I would buy another UD polish again at the $5 price in another color...the purple at Nordstrom Rack looked very pretty. I'm not sure I would pay the full $15 price...I probably would not because I hardly ever pay full price for anything!
Finally, if you're a fan of UD, keep your eyes peeled this upcoming week. They are supposed to be having a new sale every day starting Black Friday!
