Tourist in Manhattan - best way to receive a package?

I'm staying in Manhattan for a couple of days and would like to order something via mail. The place I'm staying at probably isn't able to receive mail, so I'm looking for alternatives. The place I'm ordering from ships "standard ground" (which is USPS I assume).

A quick google search led me to USPS "General Delivery" (https://faq.usps.com/s/article/What-is-General-Delivery) which seems like what I'm looking for, but if I understand correctly not all USPS post offices are able to receive mail this way. To make matters worse, the info on which post offices do general delivery isn't searchable on the website :(

I also saw something about USPS lockers, but the place I'm ordering from does not seem to support them (I can only enter "normal" addresses).

I'd be really grateful for anyone pointing me in the right direction 😅

EDIT: Some more info:

I'm trying to order a rather niche board game (https://stormthecapitolgame.myshopify.com/), which isn't available on amazon (and probably not in stores either). Also, they don't ship to my country (even if they did, it would cost more than the product itself)

I'm staying at an AirBnB and don't want to spend valuable vacation time waiting there for a package to arrive, which is why my lodgings probably aren't an option.
