Why do you charge on a monthly basis for using Wishlist Membership Notifications?

Wishlist Membership Notifications is evolving all the time and new features are added to it on a regular basis. The only way to make this possible is by charging recurring monthly payments that will help us to support future additions of Wishlist Member and WordPress. Also, if you manage to reserve even only one client using Wishlist Membership Notifications, then the monthly price is a no brainer!
