Should have arrived last Thursday after two days intransit from Michigan to Connecticut and kind of sensed something was up when it stopped tracking after the first day. The seller (Reverb not Ebay) told me he did not actually see them attach the label at the UPS customer center, but we both agreed nobody would be that stupid, right? After two days of investigation and passing lots of info about the bass to UPS it appears to have (maybe) been found on its way to their lost and found in Utah with no label. I always print my own labels, but that is really lame by the UPS staffed Customer Center. You'd think that would be customer counter 101, peel the label and slap it on the box! The claims rep told me that even if its found, they sometimes disappear again. Seller and I are kind of waiting to see whether it tracks or just shows up. It was shipped last tuesday and reporting missing on Thursday (1-26) so the 8th day from missing I think is Friday 2-2 when I believe they will consider paying out on a claim (fully insured), but maybe not since its "found" though I've seen no proof. Seller has contacted them like once a day and even forwarded me an email from a mgr. at the shipping location saying they found it on its way to lost and found in Utah (they have another in Chicago, but that would be too easy) and they were going to get it routed back to me. Still no tracking and they say even if it gets a new number it will cross-reference from the original number. Since I'm not the shipper, nobody tells me much at UPS except they will get back to me so I'm kind of stuck at the moment. Its a nice 2001 Sting bass which I've been looking forward to, but the longer it takes and gets banged around in the cold, the more I'm wondering if I'm going to like it if and when it arrives in whatever condition. With a complete lack of urgency on UPS part, not sure if I should hang in there or start trying to get my money back. The seller has been great so far and not their fault.
It’s my understanding that as far as you are concerned, the responsibility to make sure the item arrives on a timely basis is with the seller regardless of with who, or what method is used, and oh BTW, has your money. Now the seller definitely has a beef with UPS and should be screaming “blue bloody butterballs” as he may be forced to return your money if the item is lost, and could get a negative rating. Of course you want this bass, and hopefully it’s in good condition and all will work out.
Make no mistake, the UPS claim check will be paid to the shipper, not you. I would make it very clear to the seller of any deadline you have, and when it is breached, you will expect an immediate reimbursement.
