HolteI tried this multiple times in high school and the boxes never arrived at their target. USPS is probably smart enough to realize that nobody is actually ordering seven thousand boxes.
shitpoopyou can also get free USPS shipping labels/stickers, and make some ghetto stickers out of em
actually i did this in high school and this kid got a slip in the mail telling him to go get them and he never did so they brought them to his house on a flatbed and dropped them off... all 11,000 of them hahaha 3 pallets 6 feet tall each. it was amazing. i got a call to confirm that i wanted that many of them i just said yes
