The website is not set up yet for aph discounts, as that was what they said
when I called 1-866-pass-for-fun, but I did but 2 frequent fear passes for 48.00 each, the discounts are there you just have to call.
I was having the same problem, so I purchased them over the phone and they were able to sell them to me with my APH discount. Just call the APH hotline and they'll help u out.
