I just downloaded this toolbar here. There's an option that allows you to contribute X% to a charity of your choosing from the list of merchants they are working with.
One of the features on this tool bar is that is has a coupon/voucher button that appears when I'm surfing certain merchant sites. Now this is great and all but my question is: how does it know what website I am on? Is it reading my cookies? Is this even legal?
I am working as a junior DBA so I don't really know what goes on behind the hood so it would be great if someone could shed some light on this!
