For additional interaction and useability features, I found four new plugins to incorporate into my site.

Sugar Calendar

Sugar Calendar allowed me to create a schedule of events and discounts for users to easily see and plan for.

WordPress Books Gallery and Easy Digital Downloads were plugins I found for my businesses specific use-case of selling books online – the first helps me to set up an easy to navigate gallery of book options while the second allows me to offer e-book and digital sample options.

WP Mail SMTP

The last one is for backend functionality: WP Mail SMTP ensures there are no issues with email deliverability through the WordPress site.
