Shipping - cannot figure out method choices

[mrcastle]

Hi everyone. I tried looking around on shipping but can't seem to get some basic information. I'm attaching a picture of what I'm getting on my USPS page. It is offering my customer all of the methods.... it doesn't make any sense to give the option of printed matter shipping rates but I can't figure out how to remove that option. Yes, I do sell music books and will want to use the printed matter as one of maybe two options but again I just can't figure it out. Thanks again
