Does WordPress provide ways to deal with online sale/purchase?

WordPress has several membership/subscription plugins that use PayPal for payment processing – a simple online search will reveal many.

Thanks for information Naomi!!!
I am new on WordPress. I would appreciate just a further information. Do you is it possible to establish on WordPress structure a website that provides/sell on-line courses. I intend to make available around 10 on-line courses, maybe a 100 video in total, related with the these 10 courses. As a reference I have Lynda.com, but of course what I intend to do is smaller and with narrow focus.
Best!

Absolutely. Here’s a recent article with more information: https://wplift.com/how-to-use-wordpress-as-an-lms-for-an-online-learning-website

Many, many, many thanks ??
