January 21 2012 I paid $97 for an anytime upgrade of Home Premium to Ultimate through an Amazon Digital purchase. Now it isn't listed as an Amazon item and the only seller has a Pro upgrade for 275. The Ultimate upgrade is unavailable. There is this for $176 but I am not sure if you can type that product code in as an anytime upgrade. The code for my Ultimate looked like any other windows product code so it may work.
