Southwest: Can I combine voucher and discount code

[stout]

What is the best way to do this?
Southwest is running a sale to MCO for $79 each way. I need to book me, DH, and DD4 roundtrip.
I have the Southwest $25 discount code that I understand can apply to the all three of us.
I also have a $68 voucher from a flight I had to cancel earlier in the year.
Can I couple the $68 voucher with the discount code like this: $79 x 6 = $474 - $68 = $406 - $75 = $331?

You should be able to, but check the dates on that $25 discount code - mine was expired when I tried to use it last week. You put in your discount code on the first page where it says "promo code", then you can go to your account and pull up your voucher number and apply it toward the payment on the last page.
