Related: Not US postage labels, but suspicious US postage stamps, seemed to also be used as a crude currency.
A third-party seller on Amazon or eBay was including sheets of suspicious US postage stamps in product shipments, unsolicited, with full-color glossy notes offering more stamps in exchange for positive reviews.
(I took the stamps and note I received to a post office, where a manager agreed they looked suspicious, and I asked them forward it up the chain. I like the USPS as a trustworthy service and institution, and I hate counterfeiting.)
