3 day park to park question

[SPIDERMOM]

Does anyone know if it is cheaper to buy a 3 day park to park with an AP discount or the 2 day/ 1 day free from UT?

You can calculate the AP discount price by taking the online price and adding $20, then subtract the AP discount (10% for power, 15% for others) and then add 6.5% tax.
