I've been using Gumroad for almost 15 years and they recently made changes such that I can no longer sell physical products (my signed paperbacks and shirts). This was an unexpected change so I've had to establish a website to sell physical products at:

occultsymbolism.com

Please go there to buy signed paperbacks, super soft t-shirts and bundled packages!

Gumroad will remain a location for digital assets and e-book PDFs.

Thanks

Isaac
