We have a daily UPS pickup so we are not able to ship Fedex. Unfortunately, our shipping software does not let us use other companies shipping account numbers. When a buyer would like to use their account, one solution we often used is to have a label sent to us in a pdf format. UPS is preferred when we do this.
If you need a shipping estimate for a Purchase Order simply go to our shopping cart ( i.e. www.tapefinder.com) and add the items you want to the cart, enter your address and then go to the next page. Your shipping amount will be listed. Write down this number for your PO and then exit the cart.
