I've not noticed this before but my Facebook seems to have people either selling or asking for recommendations on where to get these.
People are printing them themselves with a name (probably using Cricut) and selling them.
Isn't the whole point in buying the merchandise so that some / all?? of the money goes to the charity?
It's the same with the bling Poppies. Lots of people making and selling them on eBay and Etsy but I bet most (not all) are using the Remembrance day to make money?
