Tried to sign into my Model Train Stuff account and keep getting a Shopify "This store does not exist" page.
Now back online, the Model Train Stuff store was moved from Bigcommerce to Shopify.
Now, when you sign-in, a six number code that is sent to your e-mail address must be entered.
If you don't want advertising e-mails, make sure you remove the check from the news checkbox before confirming your code number!
