I am recently in a problem with coupon codes and product custom option in Magento1.8. We wanted to offer a special discount code to any customer who want to buy products with a custom option or set of custom options selected.If any Customer buys the product and there is a custom option without SKU under that product, then customer will get discount by coupon code. Not only specific product. It should be dynamic means the customer will get discount by buying any product with selecting its custom option. I had googled a lot. I see a link http://www.madcapsule.com/blog/magento-adding-coupone-code-to-product-c by searching a lot. Here this example is done on specific product. I need a clue for above requirement
