I can't remember where I first bought mine. Maybe Target? But that was years ago.
You have to understand that there are different versions depending on whether you itemize or not, and that there are additional charges to download the state returns.
That said, I am on auto-renew. So I get a TT deluxe + State sent to me each year and this year it was $60.
The first time you use it is time-consuming because you have to enter all your personal information, employer ID numbers, interest accounts and all that. But when you use it in subsequent years it is a breeze because it imports all that personal info from previous returns and you never have to type it in again.
Last year, I did an itemized federal plus an itemized state in about 60-90 minutes.
Plus, if you itemize, you can deduct the cost of the software.
Love turbo tax.
