Product Selection based on Username

There is no way to do that in WooCommerce by default.

You would need to find a plugin that allowed you to display different products based on the user.

I’m not aware of a plugin that does this by user. However there are plugins that allow you to do this based on role. So for example you could display different products to wholesale customers.

A good plugin for that would be:

https://woocommerce.com/products/woocommerce-memberships/

Or

https://woocommerce.com/products/products-visibility-by-user-roles/

Thank you @fullysupportedphil I appreciate your feedback, and I will check them out.
