Magento usually offers a number of shipping options which I can choose from. In my case however, there are two shipping options (let's say
premium), but each one of those has sub-options if you will (for example my shop will take the packaging back if you pay an additional few bucks).
I'm thinking of something like the following:
[radio]standard - 59
[radio]premium - 79
[checkbox]take back the packaging please - 12
[checkbox]insure my package - 24
[checkbox]also, please come with two people and bring the product where I want it - 29
How can I add checkboxes to my shipping options for additional services? Is there a module for this / can I write a module for this myself without rewriting half of Magento's code base?
