Custom Item. SSA used UPS Ground to calculate 2 day transit time.
The name on the address is a 6 digit number.
There’s no Residence Inn in that zip code.
Address is invalid, and UPS isn’t possible in Buy Shipping.
Only “on-time” options are USPS/FedEx for $26.23 to $52.13
Should I just cancel?
That would be 3 strikes for us … cancel order for invalid shipping address.
This often indicates the item has been ordered for an incarcerated person.
Google the address and the name of the town.
Most prison orders go bad, based on my many years of selling books.
If in doubt, cancel the order, ASAP. Take the hit rather than lose your item.
ETA: Just noticed the address is a Marriott. Skip it! My long experience also tells you that orders shiped to hotels rarely go well.
Will cancellation for “Shipping Address Undeliverable” affect my order cancellation metrics?
Maybe, but cancellation is better than paying for shipping and losing your item.
Yes, but unless you are borderline, cancel it anyway. This smells like a rat. A dead rat. The smelly kind.
CANCELLED.
Thank you for everyone’s feedback. I figure this looked obvious, but the only thing I know is that I know nothing.
No, you don’t know nothing.
You knew well enough to consult your fellow SAS participants when you encountered a situation with which you figured out you might require some help.
You did the right thing, and we were here to help you.
That’s a bingo right there for me
Did the Buyer reach out to you about the cancellation @Setalpz ?
No response. I had messaged them about their address before I decided to cancel the order; they never replied. The cancellation has already fallen off my metrics, which put me at about a 1% cancellation rate due to my volume level last week. Very glad I cancelled.
Well done! If it was a legit order, you did everything you could to make it work. 
This is Boos Brothers territory. I would regard that as one more mark against it.
Agreed; I’ll always remember the hand you played in addressing this ongoing problem, as eloquently described in your 101024 SAS post here:
and your 021824 post here:
The continued thriving - with Amazon’s connivance - of nefarious operations like those of these infamous brothers speaks largely to why so many sellers think of Amazon as a Sociopathic Greed Machine - but it is hardly alone in that regard, as our friend @Bird_of_Paradise intimates in this 042125 post over in the SAS’ Walmart forum:
