On the Prices you can specify the unit price for at certain quantity, and ecom will automatically include this in the cart calculation.

The function I want is if the customer adds 12 of a specific product then the customer will get a discount on 10 of the 12 products and then ordinary price of the 2 other products.

In example the product costs 10 and the customer buys 12 then he will pay (10x10 - discount) + 2x10.

And that is possible with different unit prices?

No, that's not possible. The default discounts can't be used either, so you'll have to go for a custom SalesDiscountProvider. You'll find information on this in this document: http://engage.dynamicweb-cms.com/Admin/Public/DWSDownload.aspx?File=%2fFiles%2fFiler%2fDocumentation+portal%2fDynamicweb+CMS%2fDocumentation%2fDevelopment%2f(en-US)_Extensibility_API__Dynamicweb_eCommerce.pdf

Ok thanks for the information.

But that is not anything you are going to implement into the discount module?
I know that in many other systems this function is standard beacause it is often you want to give a discount on quantity of a specific product.

Sorry for the late reply. There are no plans for including this no, but if it turns out that there is a high demand for this, who know, maybe sometime.

Do you have any tips about how I should create my own discount provider?
The price should change when the customer adds a specific quantity of products (as in the picture).

The discount should be presented as the attached picture.

Hi Magnus

Could you get the same result if you use variants of the t-shirt with a custom field called 'unit price'?

Main product: T-shirt:
Variants:
1 t-shirt: price: 59, unit price: 59
4 t-shirts: price: 196, unit price: 49
10 t-shirts: price 300, unit price: 30

Then you could either just have those variants (which means that 12 t-shirts would look like 1x10 + 2x1 in the cart) or you could make a custom notification subscriber that listens for cart events and merges the order lines.
