I had thought I was signing up for the free substack subscription by a writer, and if you signed up, you would be able to download his collection of previous essays. However, when I got the confirmation email, this link was in it to download the free PDF collection. I didn't realize until about 4 hours later that I had a later email arrive noting that my credit card had been charged for $50. Got refund.
