Different Feature Ad pricing for different categories
I am working on a project using the Classipress.
The pricing model is similar to gumtree.com.au so members is free to post an Ad but needs to pay extra to be a feature ad. The feature Ad pricing for each category is different (e.g $20 for 7 days for Automotive Feature Ads and $10 for 7 days for Computer Feature Ads )
I am aware of different price model for "price per ad" and "price per category" but it seems it cannot fulfill the above. Any ideas?
