Commerce, different price based on quantity Is that even possible?

I read that Drupal 7 has some discount modules for that, but Drupal 8 doesn't have anything. Is that true? And maybe someone can point me in the right direction how to achieve this goal...

I have found this post: Drupal Commerce - product attribute price based on quantity which suggests using https://www.drupal.org/project/commerce_price_table module but nothing for Drupal 8.
You can set a Promotion based on Product's quantity if that's what you're looking for. Just give a go to commerce_promotion module (included in Commerce 2.x core) and enable set conditions as on the picture below.
