Magento-Custom shopping cart price rule - Buy 2 different products and get those for flate rate?

Question

I want to set up different kind of price rules(shopping cart price rules) for my client. I tried default magento's extension, but I couldn't. when I searched in the net, some solutions told that using observer can solve my problem. But those weren't enough for me. Let me explain one of my problem.

Buy 2 different products and get those for flat rate.

Say, Product X is 700 and Product Y is 500. When customer buys those 2 products (Total 1200), he can get both products for 1000.

is there any straight way to do this or should need to create custom module with database table and observer?

Answer 1

1. First Specified Your X and Y SKU and put this condition and action and apply discount amount.
2. If you don't found SKU in condition, then change in the SKU attribute to apply shopping rule to YES
