Hi,
I just wanted to post interest/need for a dynamic pricing feature like described in this post:
http://www.gravityhelp.com/forums/topic/dynamically-change-price-of-an-item
I would love to see this feature in the future. The administrator mentioned that no one has requested the feature so I wanted to reiterate that there is an expressed interest for this.
Thanks and keep up the great work! :)
