You can most definitely create a website on Shopify and not sell anything on it. However you would still need to pay for it monthly but you can get away with using the "Pause" Shop feature that basically keeps your website live but disables checkout instead of paying for the 29$ monthly.
Hello, Could you please provide a little more detail about how to make a site the does not sell products? I am very interested in this format. Would I just need to remove the code for check out and pricing?
