Sure is: https://www.visa.com/supplierlocator/index.jsp

I'd first start by entering stores you know are eligible: IE: Staples, Office Depot, Quill, Reliable Office Supplies, etc. Note the merchant category codes, since you know those will be allowed.

Next, clear all of the fields and under Industry Segment, choose Office Supplies/Stationery. Throw in a ZIP code and search. If buying online, try looking for where their corporate offices are and use that ZIP.

Some interesting results near where I am today:
Hallmark stores
run-down motel
few tourist trap crap shops
head shop(!)...I guess bongs are "office supplies"
used CD store
the GI department of a local hospital
car wash
soap & perfume store
candle shop
and a sex toy store.

YMMV... which is why I suggest searching known good "Office Supply" stores on that list, write down the 4-digit MCC# from those, and make sure where you want to order from matches.
