I purchased turbo tax home and business from amazon for $75.26. I see that e-crater has it for $29.99. The only thing i see different is that it says e-file. Let me know. What is difference in functionality between the two products for the large price differential?
Federal tax returns can all be e-filed.
The Home & Business software is the Desktop (CD/download) platform, and it does include one free state tax prep program. You will be required to pay to e-file your state return; federal e-file is free of charge.
There are multiple online retailers, as well as brick-and-mortar retailers that are authorized to sell TurboTax products. In addition to purchasing directly from TurboTax, you can purchase from Amazon, eBay, Office Depot, Sam's Club, Costco, and many others.
Here's a link to the TurboTax webpage for this particular Desktop edition. It looks like TurboTax current price (1/29/2018) is $109.99. But shop around, as many other retailers do offer discounted prices.
