All Things Profane and Sacred

I'd like to shout out a big fuck you to my homies at half.com-I've been trying unsuccessfully to buy a certain book I need NOW for a few weeks. I place my order, I pay for it, I get a confimation email, and then, a week later, an email that that fucking seller backed out. No reason is given. There is no way for me to warn other buyers that the seller is a piece of shit. There is no way to contact the seller and let them know that they are a piece of shit. Fucking ridiculous.
