Priority is 2-3 days transit, usually two. Sorry but if all you have is a PO box we just can't help you.
But, I need you to do the following if you do need a return. And if you are not satisfied send me a message asap letting me know whats going on and I will take care of it.
Do not return the item before contacting me. After you have reported a problem or the want to return a item wait for our answer and we will promptly reply to you! I know this sounds like a lot. I will take care of any problems and work through them in a timely manner. I want you to be satisfied because it is the only way I will be satisfied!
