I am suprised to see that no one else has ran into this issue. I have an issue where I need to change a price field on the fly. In other words if someone buys 1-24 of an item, the price is $5.00. If they buy 25-99 the price is $4.50. I have not found any hook/filter than will do this. I can code it out in PHP but that really does no good using Gravity Forms as it seems you more directed into using their hooks/filters and modifying them to fit your needs. Does anyone have any recommendations as to what direction I need to go?
