Is there a way to calculate overnight shipping on the USPS website? I have a customer who wants to order a handfasting cord, but needs it by October 4th so she would like it done next day, but I can't find where to calculate that. I would obviously need her zip code correct? I have it in my policies that I do rush orders, but this is the first time anyone has ever requested it.
I also normally ship priority mail cause it's cheaper, but is there a different way I should ship it? Thanks!
