Chanel Top Coat Velvet

For awhile I've been looking for a matte top coat because it just looks fabulous and I know there are other brands out there but I saw this one and something about it just screams BUY ME. Everything about it looks elegant and fabulous. The all black bottle with beautiful white writing on it. But is it worth the price? Reviews tell me that yes, in fact it is!
With a quick google search, I find two sites that did sell it before it sold out (Nordstrom, and Neiman Marcus) so it appears that the only place you can buy it is eBay and Amazon. Of course since it's limited edition and sold out on those websites the price on eBay and Amazon are jacked up a bit compared to the $27.27 on Neiman Marcus. Will I buy it though? I don't know, that's a tough one because as much as I want it, it's a bit ridiculous for a nail polish top coat, but can I resist the urge to buy something so beautiful!
