These guys are nasty sneaks. They use bait and switch claiming it will cost < $10 to efile both IRS and Ca state. I got to the end of the process, and TaxAct pops up a message that says my return is no longer free, instead it will cost $8 for Federal and $15 for California state to efile OR PRINT.
I was stuck, so I decided to just efile the Federal, then printed it and used that to free efile the state through the FTB website.
The interviews are also poorly structured and you get asked the same thing over and over again. Would not use again.
