Setting up Discounts for a number of items

[ShopTester]

Hello,

 

I've started working on Prestashop Cloud version and looking for some help regarding the following:

 

I would like to give a discount to customers that buys from my store with the following conditions:

 

Buy 1st item you get 10%

Buy 2nd item you get  20%

Buy 3rd item you get 30% in max total.

 

If the customer buys more than 3 items they will still only get 30%

 

I went through the Price Catalog, and set up 10% discount on Qty 1 item

But testing it in the store, it doesn't seem to be working.

 

Any help or guidance in setting this up is very much appreciated.

Thank you very much for your time.
