How send eBay products to my post office box?

If I register as guest user and buy the stuff I want. WIll it send to P.O. box that I have in my town. Im thinking about buying right now, so I haven't seen the buying process to see anything yet. Oh yeah I don't live on a official street(it's kinda like farmland) with no mail box so the registering account to buy anything be okay (I'm talking about the buying process, stating were to send the stuff)?
