According to the UPS tracking number, they were supposed to be delivered by 8/21. Following the tracking on the UPS website, the liners reached our local depot on 8/16. And there they seem to be sitting, still.
So, my partner calls UPS and says, "Hey, where's our catbox liners?" UPS says, "I dunno . . . call the shipper and start a trace."
Come on, they're at the freaking depot! Contact the freaking depot and have them find the freaking package! I could see having us get a trace if the package was stuck somewhere enroute, but it made it to the next-to-last step - next step would be "out for delivery!"
In good service, though, the seller has agreed to start a trace right away.
