I consulted with H&R once, like Randy, I was quoted some astronomical price that was literally more than what Mike made in a week. I went online and filed my taxes for like $15 and save one time have done that every time since. You can also go to the local IRS office and have them prepare and file your taxes for free. I had to do that in 2010 for my 2009 taxes when my records and the IRS records were not the same, and they were able to sort out that I had gotten one of those voucher claims though I had not received the money or notice...
Like others have said, once you sign the documents, you are responsible for what is said. There's something to be said about being poor like me...less headaches at tax season...
