Does craigslist allows you to post affiliate link? If yes then which section can I post affiliate links?
as far as I'm aware, craiglist doesn't like affiliate links and may ban your account but I've seen some affiliate links there from time to time
Craigslist does not allow affiliate links. in fact, in most job sections they plain out warm their users to ignore affiliate links before you can even view the job listings. Of course there are ways around this. Register your own domain and use domain forwarding. Also it would be a good idea to write very effective ads that don't look like affiliate promotions. There is a ton of information on how to properly do this in forums and of course you can craigslist spy on other effectively written ads.
Craiglist has started posting warnings to people, and it's been tapped so much that I think you might want to move on.
