Agreed - saying something like "Having a storefront on Shopify would normally cost you an extra $20/month. TinyStore does this for $5/month." would sell pretty well I'd assume.
Exactly this, didn't know that Shopify had a headless mode that does not include the storefront, so the question was: why not using the default Shopify storefront?
Same here. Shopify's landing page for Lite says "Shopify gives you everything you need for just $9 USD per month" - so I couldn't figure out what this was for.
Lite not having a storefront should be front and center on OP's page.
