'Add to Cart' that doesn't capture payment

I’m looking to test a product. I would like to create an ‘Add to Cart’ button, that does not collect payment, but can collect contact information for follow up when the product is available. Any ideas?

Thanks!

Just make a custom contact form page., if you are not making them go through the checkout process

And either redirect the /product url to the contact form /page

Or customize the product page to contain the contact form.

For a broad example see the back in stock notification customization.

If forcing them to go through checkout use line item properties or cart attributes.

If you need this setup you can contact me by DM, or via info in my signature. Please Provide context: post url, shop url, theme name, problem description,etc.
