Great advice! I was thinking of this on a smaller scale yesterday when I was making purchases at a book fair hosted in a museum. The authors were selling their Zines, Chapter Books, leaflets… etc… I was excited to support the artists who were producing outside the normal means (publishing companies—not that I mind those). Anyway, one artist only accepted Venmo & cash. Luckily, I had cash. Another had all the payment options & I used my Cash App. It made me think about flexibility—
