If you have any products set to use digital-delivery features (File Download, Send Stored/Generated Codes, or product-specific Redirection), then the tangible-goods-only subscription plans will not be available to you. You can disable any digital-delivery features in your product settings to make the tangible plans available.
If you would prefer to show buyers a thank-you page on your own site rather than the standard E-junkie thank-you pages, then you can specify a Common Thank-you Page URL in your Admin > Account Preferences, and that setting does not count as a digital-delivery feature.
