Renewing Domain, no payment info required?

I'm the owner of www.dogsandchats.com. It is now time for my renewal of the domain name. I set it to renew, and renewal process is now underway. My question is, if I have no credits, will it renew? I couldn't find anywhere that says it costs money to renew, or how much to purchase if needed. I'm hoping that if it does cost money that I will be notified with enough time to still renew. (3 days left)

Is this your 2nd year? Maybe you will get the 2nd year free for having high activity.

Yes, it is my second year, and the site does have high activity. Is is sometimes free? The members are ready to purchase credits if needed, but I need to know before it expires...... Hope you're right though!

Did you book the site again, without spending any credits?

Apparently my site has been renewed, no credits spent! That's awesome!!
