Yes! You can post ads on OLX.ph for free! There is a certain number of ads you can post for free though, and the limit varies depending on the category you are posting in.
How do I post additional ads then?
The website is designed for your convenience. Upon reaching the limit in a particular category, you will be redirected to a page where you can purchase a Paid Ad Slot to continue posting your pending ad.
The cost of Paid Ad Slots vary depending on the category you're posting in. You can check the free ads limit and cost of single slots for each category here.
Paid Ad/Slot Packages are also available if need to post several additional ads!
