I am trying to make a block which shows two products in it with a rule that if a customer bought these two products together the total amount will be reduce by some extent.
e.g. if product A is of $100 and B is of $75, then both will be buy together for $150.
Can anyone has an idea how to apply these kind of promotion rules in magento. I really need to do this as the client need this kind of functionality on its product view page.
I want something like this.
