You have self employed for $94 but Costco has Home and Business for $64. Why can't I use that from your site?

You'll often find the TurboTax software (CD/download) editions at cheaper rates than on the TT website.  That's because the "big box" stores discount the prices significantly to get you through the door in the hopes that you'll purchase other items.

Here's a list of places you can purchase TT software:

And I just looked at Turbo Tax Desktop CD/Download program for Home & Business.  Home & Business is 109.99.  

The Online Self Employed version is 94.99 and that is only for Federal.  State is an extra 39.99.  Self Employed is the same as Home & Business just a different name.

So buy Home & Business at Costco or wherever you can get a good price.
