If you use turbotax online instead of buying or downloading the program, the e-file is included in the cost of the program and you don’t pay additional for it. If you have an account with Vanguard, you can get a discount on turbotax online.

I efiled my taxes and it was painless. You can get your refund faster if you efile and you don't have to wait in line at the post office. You can e-file now and wait until mailing in your check as long as you get it postmarked by the 15th.
