Have many people have you asked how they get the free shipping tape from USPS!
And not one person has helped you, right? Or they tell you to order the Military kit-do not do this! this kit includes a tiny roll of tape and is meant to be used for Military shipping.
Keep in mind that the USPS has Priority Mail boxes for shipping. These are free. Free.
If you have a bunch of boxes that you save and want to recycle for shipping sales, then you can use the priority mail sticker to mark you packages as Priority Mail. I just cover any existing bar codes and personal information. These are available on the USPS website. Below are the links, currently they are available in rolls of 520 and 1000.
Now, the tape. The tape is not online. You will not find it. You have to call and request the roll of tape. Keep in mind this tape in only meant for use on boxes that are not already marked as Priority. The purpose of this tape is to identify your recycled package among all the other packages. The tape is lighter and not the best quality. Please tape up your package with your regular shipping tape and follow with the USPS priority mail tape only to identify the package as needed.
If you understand how to use the free USPS Priority Mail tape correctly, just call customer service (1-800-275-8777) and place your order.
