I must be really behind what's going on in the nail polish world, because I didn't know Urban Outfitters carried all of these brands of nail polish available to order on line!

They also have some nail art and treatment products available, as well as their own house brand. If you click on the link above, you can view them all. I Google searched and it looks like they often have coupon codes available for 10-15% off. Have you ever ordered from them? I wonder how their customer service and shipping are. And don't make fun of me for not knowing this already!
