another thing I just noticed: on his original Post Office receipt, it looks like he paid for the clear tape AND the shipping label, which would mean that they weighed his package and gave him the the shoes back and shipping label and the tape for him to affix himself. So he could've taken the shoes out, taped up the box, took a picture of it, slapped the shipping label back on and then "dropped it off". And since he just weighed and paid for the label right there with the clerk, that clerk probably just took it without weighing it a second time.
