I need to add a custom field to the checkout pane. I need to have a "I want receive special offers and news from the online shop to my email" -checkbox.
Is there a module to do this? I couldn't find one. Has someone implemented this kind of feature? Any help appreciated!
I'm using ubercart 2.x.
I found this:

but can't figure out what it does..
