Charge for featured listings per category
Hi all, I have a little dilema. Currently all ads are free on my website, unless the seller wants a featured ad, then they pay for featured. However, I have some categories which don't have many ads, some categories with no ads at all. So as an incentive, I wanted to offer free featured ads in those categories, whilst still being able to charge for featured ads in all other categories. Would this be possible at all?
