How we determine the cost
The cost of your promotion is determined by the category selected for your event. Another factor is the size of the audience for the site to which you are posting. You can quickly determine the cost of a promotion by clicking "Promote Event" on any calendar and entering the title, category, and location. Eventually you should be shown the price of a single promotion, a bundle of promotion credits, and a list of the publications where the event will be syndicated.
Current Pricing Plans (based on the selected Category)
The "Community/Local" option is the lower priced category. Selecting only Community level categories will give you the lowest price for you online promotions on our service. This is how provide discounts to local and community non-profits.
A: Our prices are based on the category selected for the event. When you are first quoted a price you have only selected one category and we base the price on that category. While creating an event, you can add up to two more additional categories. If those categories are for a higher priced plan then the price for your event will increase. It is possible that the edit you made involved adding an Enterprise level category.
