Hi guys, I've heard about this "free plus shipping" method where people create a landing page for a single product and upsell in the next pages. I'd like to know if it's required to make a full e-commerce store before creating and promoting the one-product funnel. Are people having success with this or customers are more hesitant when they realize the "free" offer is not actually associated with a proper Shopify/WooCommerce(or any other platform) store? The idea here is creating different one-product funnels to test the water and then build a full store around the winner niche. I'm not sure if successful marketers do that. I hope you understand my point, I'm not native English speaker. Thanks all!
