I'm not sure exactly how you can accidentally include an affiliate tag in a link. That and the rather over hyped title really do make it seem like this was rather deliberate. If I were you I'd either edit the link (if that's possible) or delete and repost.
I guess you should be given the benefit of the doubt this one time, but I really don't think that's acceptable behavior. Hopefully an editor will notice soon and change it.
I've listened to TripleFi 10 too and they're even more amazing, if that was even possible.
Fatwallet has a discussion on these with a very green rating for those in doubt about the real hotness of this deal.
