UPS already tried doing this a few years ago in Brooklyn,[1] but not Manhattan apparently.
I was subjected to this a few years ago.
Instead of being greeted at the end of the day with my shiny new $300 phone, they left it in a pile on the filthy floor of a local bodega three blocks away. Then, after finding it, I have to wait in line and have my ID scanned and sign for it. And I paid for overnight shipping but if I don't rush home, I have to wait until the next day.
My neighbor hated it more than I did. So, she started "stealing" her packages from the bodega. It turns out that if you don't sign for the package, they return it to the sender after a week and you get a full refund. So you can easily double dip by not signing for it and also getting a refund. And the local business is responsible for package being lost.
After two months, the local bodega stopped hosting packages, presumably because they were having to eat the cost of losing packages. Since there were no other businesses nearby willing to do this, UPS was forced to resume delivering to our building.
While this is an effective way for people to shut this kind of thing down, I'm sure it must be illegal. At least if you get caught, it is fairly deniable, since the package has your name on it. But it is probably illegal to interfere with a package being delivered.
Please do not do this. You are stealing from the merchant.
