Amazon.com has the TurboTax Deluxe Fed, Efile and State 2013 with 10% Refund Bonus Offer for $39.99 for Prime Members with Free Shipping. The download version is $39.99 for non-members.
Use some (or all) of your federal refund to purchase an Amazon.com Gift Card from TurboTax and TurboTax will tack on an extra 10%—so $500 would become $550.
