Yes, I did post this a couple days ago but that thread expired when it went OOS online. It's back in stock now.
And yes, you can get this in warehouse for $9.99, if you can find it. You're essentially paying a premium for shipping, convenience and availbility.
[Edit] - Sorry all, looks to be out out of stock now.
