Tools you buy once and actually own, and designs worth looking at. Even Jotweft's custom planner is yours to keep as a print-ready image. Nothing you buy needs a subscription to keep working, and one person answering the email.
Digital things are on Payhip. Printable and printed things are on Etsy. Jotweft, the optional planning service, runs on its own site.
It won't all be planners.
