Today my wife and I went to Best Buy and bought the latest version of TurboTax, just like we do every year. Just before the installation, we discovered that Turbo Tax is available online for $20 less. Since our software was unopened, we were able to return it.
We used the online version for the first time, and highly recomend it. You don't have to install any sofware, and can access your tax filing from any computer. All of the version like Basic, Deluxe, Primere, Home Business, and Business are all available online.
