ok...WHen I looked it up I was under the impression that h should be checked...The only reason I care is if I do the CF online I can make the process of sending a little quicker(they can use a bar code instead of typng it all out)...or even send from my mail box(I just prefer to go to the PO) and that way I have a sticker with the date clear..as well as knowing if a error in shipping is made they still need to make good
