1. Define where extension files are located.
There are 2 places where you can find extension files:

One of the Magento 2 features is Customer Group Price (Tired Price). It allows you to set different prices of products in accordance with their quantity as well depending on customer group. E.g. define lower prices for wholesale customers who purchase 10 and more quantities of the same product.
In order to set Customer Group Price, you have to configure them on every product separately. To do this you need to:
1. Login into Magento 2 admin panel
2. Navigate to Catalog > Products
3. Select a product you want to define prices for
4. Under the "price" input click on Advanced Pricing link
5. Manually specify a price for each group and qty
It is not very convenient, especially in case you need to change prices on a huge amount of products.
