I had my doubts I would get a result, but I purchased Ghostbusters I for 6.99 on the weekend (Canadian iTunes store). There was no sale for II. This morning, featured in the stores, was both I and II together for 9.99. It was quite a bummer so I contacted iTunes Store support (which I had never done before) and told them about it. So they have refunded my 6.99 purchase so I can take advantage of the combo deal. Just thought I'd share in case anyone else runs into a similar situation.
