Yeah, I think you're going to have to walk in to ask that question. Although I would expect pay to be negotiable. Furthermore it probably varies from city to city or state to state depending on what is convenient or more effective for them. Besides, walking in and asking that question is a great way to tell them you are looking for a job.
I don't work there at this moment, but hopefully i get the job and if i do I'll make sure to get back to you on that
