Shopify is changing some things. They are doing away with 'Customer Accounts', so you won't need to log in using a password. You'll get a 'one time passcode' sent to you that you'll need to input to place an order. This may slow down the ordering process for chassis sales. This change is supposed to be implemented by the end of May. I have zero control over this. If you find that you are having difficulty in placing an order, email me at dcashmer@gmail.com. Overall I've been happy with Shopify but if it makes ordering harder, I might be looking for a new system.
