Deluxe vs Basic Turbo Tax

The last few years I purchased Deluxe DESKTOP Windows version of Turbo Tax, yet each year the program says I make our better with standard deduction than submitting my few deductions.  This year my tax situation is not that much different.  I had a small increase in pay, similar donations to good will and tithes.  Should I go for the Basic version this year and save money?  The only great purchase I paid for was a new roof, but it does not appear to be deductible (sad to say).  Deluxe verses Basic.  It doesn't appear I am eligible for the free version.  Also, our state does NOT charge income tax, so I would not need any state forms.
