I need to add the option for customers to select a delivery date before completing their purchase. I tried two apps that said they were compatible with Shopify Lite, and neither worked. This can be as complex as having an actual calendar or just adding a custom field to the cart/checkout stage. I can't seem to find a way to get anything to work with Shopify Lite or the pop-up cart style. PLEASE HELP!
Please note this is for Shopify Lite Buy Button - I don't use a Shopify theme.
