Yup, same here. First time this has happened...
The fast shipping was one of the deciding factors in my decision to order from them. It's prob due to their sale and not having the stock which if true really annoys me. It's very annoying when a company lists a product as if they have it currently in stock but are in fact out. Your order then sits there in limbo until they get more product in. If they mentioned that possibility on their site you'd at least be aware of that possibly happening. Some sites won't do that though as they know they'd lose sales to people not wanting to wait. Fishy business practice I don't very much care for. Not saying that's what's happening here but it's looking that way.
