Get your taxes done using TurboTax

They are not a licensed reseller.  At best you are getting pirated software, at worse, hacked or compromised software.  For downloads, stick with legit retailers like Amazon, Staples, Office Max and Best Buy.  For boxed CD copies, any US store that sells the CD in store is probably OK.  (Target, Walmart, Costco, etc.)  Most legit retailers still discount significantly from the turbotax list price.
