I'm trying to figure out how to display a custom message at checkout that would appear once someone enters their address. (based on state preferable, but having this happen based on zip would work, too.) What I'm trying to do: If a customer is from California, I'd like a message to appear with a prop65 warning.
Has anyone done anything similar to this? I'm trying to figure out how to code this in my site...
Thanks for any help!
I'm sorry, but it is not possible to show a message based on the address or state on the checkout page. You could show this information on your customer's cart, or even at the checkout page, but everybody will see it, even if it is not relevant to them.
Some ways to edit the checkout page:
You can use the translation system: http://docs.shopify.com/support/settings/3-checkout-and-payment/can-i-customize-my-checkout-page
Or use custom checkout CSS to show text or an image: http://docs.shopify.com/manual/configuration/store-customization/checkout-css
