2 for 1 Buffet

I bought 2 books and I am going with 3 people. The question I have is when we use a 2 for 1 buffet coupon, will the 2nd coupon for the 3rd person be given at half price or do we have to find somebody on line to help us use the 2nd coupon?

It will say on the coupon if you can get 50% off of one.
