Get your taxes done using TurboTax

I don't think it was ever $20 for the download version for an additional state.  It was $40, but they just raised it to $45.  This is a typical Intuit trick, where prices are raised in mid-March (if they are having a good year) to nab people who file late or have more complex situations where they are still waiting on documents.  In the future, if you aren't disgusted by the Intuit pricing policy and deceptive advertising, just buy the additional state earlier in the tax season at the lower price.
