On each product page there is a section for Shipping Notes
This section is for stores who use our feature to print a packing slip to put in with the order when it is shipped. The customer will not see this message anywhere else.
This allows you to add a custom message to the packing slip, for example:
Please note, we only accept refunds within 30 days so if you need a different size, please email firstname.lastname@example.org and we will provide an address for you to send it back to."
