I'm currently using Magento 1.9.2.2.
I want to create a rule for giving a discount if a user adds 2 items of the same price to the shopping cart.
For example, if a user adds 2 items to the cart with a price of $19.95 the total amount will not be $39.90 but $35. Also if a user adds 4 items with a price of $19.95 to the cart, the total amount adds up to $70.
A programmatical solution is also fine if this cannot be done in the admin panel.
Thank you in advance.
