Update: It's gone! See comments and attached photo. I got mine, you get yours?
If you are a deal shopper you have no doubt seen that the prices keep falling on the HP MediaSmart Server. The EX470 is down to $299 at retail stores. HomeServerHacks.com alerted me to this deal.
You had better hurry though. I know the deal at OfficeMax is good until 11/29 but I'm afraid that stock will not last until then. This deal is frontpage on SlickDeals.net today and FatWallet has a discussion about it as well.
Check stock at Officemax.com by adding the EX470 to your cart and entering your Zip Code. This should also allow you to check shipping charges. If you have a Staples in your area you can ask them to Price Match this deal.
