Last year, Intuit sold me an online version of TurboTax, and now is keeping my data with uncertain security, when in every previous year I had used a stand-alone version. I specifically asked for a stand-alone version and was told that the Web version was the stand-alone one (a lie). Intuit also soaked me for three invoices, which they refused to address, and told me it was all my fault - not a happy customer. I submitted a complaint, but that was ignored, too.
