50% off (lowest price so far this year)
Plus: $14.97
Freelancer: $22.47
Premium: $29.97
(state an additional $18.50 for any option)
Expires Feb 28, 2018.
My recommendation: lock in this a return at this rate now (do not pay yet) and then just delete and add a new return if there is a better deal in March.
Prior threads have indicated that we are not likely to see the same deals as prior years ($10 fed + state last year) due to a change in ownership.
