To create a QR code for printed materials and signs:

• Go to Webmaster.
• Choose the Page to which you wish to create the QR code link.
• Click the Download QR Code icon at the top right of the page, and it will create a graphic and download it.
• Go to your Downloads, open the file to see the QR code, and copy and paste to printed materials.

To create a QR code directly to a Product in your Store:

• Go to Webmaster.
• Choose the Store Page.
• Find and select the Product.
• Click the Download QR Code icon at the top right.  

Note that if you are trying to put links on social media or email, it is typically better to use a link rather than a QR code.
