Again, Lloyd throwing a hissy-fit/whining over nothing.. admittedly, he had enough boxes for the imagined "crisis", but decided to blame someone else for his own negligence.
USPS provides the boxes for Free, and with Free delivery IIRC. WTF else could someone want? The boxes are clean-looking, even attractive, compared to plain tan cardboard. Some styles of USPS boxes don't even require tape to seal them shut.
UPS fails in most situations to deliver anything quickly and without damage, IME.. they have a 5-day work week, so all domestic items basically sit in one place for 2 days minimum. The majority of over-5 lbs packages delivered by UPS, the contents had severe damage, destroying some very expensive electronic test equipment and other valuable items.
USPS has online shipping label services to enable shippers to print the labels with Free Delivery Confirmation, they deliver 6 days per week and independent haulers are moving mail 24/7/365. USPS will also pick up packages if one simply goes to the effort to arrange pickups.
As PM mentioned, USPS is self-funded (postage fees support USPS, not federal taxes), not that facts are of any importance to Lloyd. Lloyd is free to spend his money any way he wishes.. ULINE and other companies have all the shipping supplies he will ever need.
Now would be a good time for him to put his money where his mouth is.
The response he received may have been generated by software.. why would anyone want to hear or respond to a whining complaint about Free products and services?
There are unscrupulous fuckwits that take the free USPS Priority Mail boxes, then turn them inside-out to save a few cents by using the box to send something by Parcel Post.
