If they do sell at the door it will cost more anyways. So its about the same.
As long as the show isnt sold out
If they still have tickets for the show, yes.
If you purchase tix day of show at the door it usually is more. You should check out the website for prices and availability at the venue prior to the show. A lot of venues do have box office times days and weeks ahead where you can purchase tickets without processing fees.
