Wait. Free packing supplies? Free tape? Can you explain? I've mailed hundreds of priority packages and have not heard about this.
BTW, I tape the hell out of the box. It would be obvious theft if anything ever didn't show up in the box.
Yes I can.
Whenever you ship priority, boxes and tape are included in the flat rates. The boxes are usually found on the priority kiosk and the tape is behind the counter, just ask an employee.
You may also take home boxes as well, as many as you'd like within reason. If I remember right, you can also have supplies sent to you from USPS's website for free as well, though I haven't done this personally.
When I ship something small, like a Spyder/Benchmade/ZT, I will use one of the priority wax paper envelopes to wrap around the box, tape it secure, and it will usually be thick enough to where it will no longer move around the small priority boxes. If it's still an issue, I'll take some of the monthly literature you'll find in the pamphlet holders strewn about the post office, ball one or two up, and use that as some additional cushion/packing.
The only issue I've encountered is that the priority tape is colored and can not be used to adhere a printed packing slip to your box because of this. My post office used to let me use their clear tape same as they would the priority but they've been "cracking down." Despite the priority tape being the same exact tape, just with the addition of their brand, which I would think costs them more...Due to this, I'll bring my own clear tape just for the label.
It really makes using priority a no brainer. I used to ship standard ground or whatever they call the baseline shipping and between the boxes, packing, and tape, and the time it took to acquire these things it doesn't make sense to send it any other way. Plus, it's faster.
