To make the click & collect/BOPIS installation process as simple as possible, stockinstore will provide you with a theme files package.
The package is setup with the same folder and file structure as your theme to easily identify and copy the required code.
The unique site ID and widget IDs are obtained from your stockinstore admin area when you sign up.
You will need to create a new shipping option within admin for Click & Collect.
The stockinstore team will handle the styling from here.
