I've used Turbotax for 15-20 years now, and the cost seems to be fairly consistent the entire time I used it, between $60-75 depending on the paperwork I had to file that particular year.
Note to DUmmies, you DO know if you don't make above a certain amount of money, you don't have to file, right? I figure most, if not all, DUmmies would qualify.
But then again, DUmmies would pay $50-100 dollars to file just to get back a $25 refund...
