I usually refrain from the threads about the various carriers, but I must say I have had the best of service from USPS. Nothing lost and I receive 2-8 packages per week mostly via Priority Mail.
I have notice that deliveries have been slowed apparently because of the bad weather up north, but only by a day or two for me here in TampaBay.
UPS, on the other hand, has been the worst in my experience.
Did I tell you about the temporary UPS driver who left a package for me on some other person's doorstep, blocks from my house on Christmas Eve? Delivery was updated on line, claiming he'd left it at my door (where I'd been waiting for hours for the package).
Only the kindness of a complete stranger, who found the package at his door, made my holidays happy, sniff, sniff, as it was an integral part of my reloader that was misdelivered.
Oh yeah, that guy doesn't now and won't be working for UPS next Christmas.
But, USPS, they have been great, at least for me.
