I don’t know how long this will last, but right now former H&R Block TaxCut fans can get H&R Block At Home 2009 Deluxe Federal + State for only $25 from Amazon, including five federal e-files and free Super Saver shipping. Retail is $45.
From the description: This is the Deluxe version, which handles things like home interest tax deduction, donations, and investment income. Imports data from TaxCut, TurboTax, Quicken, and Microsoft Money software. Compatible with both Windows and Mac OS X. Includes H&R Block Audit Support.
* You can save another $1.26 and download it directly onto your computer if you have Windows.
