We haven't had anything confiscated, but I have some angry customers whose "three day" packages took two weeks. This may not be gun-related shenanigans, however. I get a dozen e-mails a week saying that UPS will have global shipping delays because of storms. It is weird that a package from Alabama to Oregon is affected by the storms in Kentucky.
We tried to get rid of UPS during the whole Brownell's deal when they first started closing accounts and confiscating packages.
UPS backed down on that, I thought.
It wouldn't have mattered, some customers still prefer the slower, more expensive, anti-gun UPS to USPS, and we had to bring it back within 48 hours. People would rather risk not actually getting what they order to ... honestly I don't know what problem people have with USPS when it comes to parcels, but there must be some reason they prefer FedEx and UPS.
I have had an unusually high number of letters and bills get delayed or lost by USPS through the years (My old water company switched to postcards, and I only recieved mayber one bill out of every 10 until they switched back), but I haven't had a USPS claim of any sort since Christmas of 2020, and most of those got magically "found" right after the claim.
I've posted many times that they are the cheapest and most reliable carrier. They also have to follow Federal law, and UPS follows "policies" that have nothing to do with law.
