I'm not eligible to post in FS section yet but I need to sell my stuff as soon as possible because there is something that I have to buy as soon as possible, I don't wanna pay(premium membership) for selling my stuff. Do I have to wait until I get permitted?

 

You don't have to pay for full premium, you can get the Classified Posting membership:

am I gonna be able to stop paying 1month from now?

 

^ Yes you will, however this option will be going away soon to combat potential frauds and scammers on the forum.

 

Thank you!!
