To be clear, this about problems with the US Postal Service, not UPS: I recently shipped out two items USPS. In one instance I had to refund the buyer's money because it just never showed up (reputable, long-time TBer with 100% positive feedback in over 100 transactions). And it just happened again, but this time the buyer was lucky enough to receive a call from someone else who was delivered the package. Finally, in a non-TB related delivery -- I ordered something off the web. I found the package several days later, placed behind my trash can, a good 20+ feet from my door. I don't take out my own trash, so it would have been thrown away had I not noticed it. The items I sent were cheaper items, so I didn't feel compelled to send them UPS/FedEx, but I'm now crossing USPS off my list and I encourage others to do the same.
