Tried to sign up for this, but it puts you directly into a two week trial for free, and I can't find any way to tell it that I have a promo code so that I can pay for the year. Any suggestion on what I might be doing wrong?

Just in case anyone else runs into this - if they are running a promotion at the time (in this case a Veteran's Day sale), they give you the code to enter, but then the system automatically applies the discount - which somewhat begs the question of why they give you the code. You can see the discount in the not immediately apparent invoice that is generated.
