Members-Only Shop for Patreon + WooCommerce

Plugin settings (all optional) to configure once you install. The "Product Category Slug" is the category of your shop that's for Patreon members only.

If someone adds a members-only product to the shopping cart (and isn't logged in with Patreon), they'll get this warning (output is standard WooCommerce notice, styled by whatever theme you're using).

If they try to check out, WooCommerce will show this error instead of the checkout steps, and prevent them from continuing.
