@Blue2u, I've closed kobobooks.com since I posted, so can't I'm sorry.
But also I'm not sure that one could successfully post a link, because the info is on the 'Thanks for purchasing' page that comes up after you've bought something. So I don't know if that would link successfully, but hey, someone needs to give it a try after their next purchase.
But, thinking about it a bit further - no link was in the actual promo. The promo was as I posted it .....
So, how does one do this?
