Thanks a bunch for doing this - I'd been toying with doing something similar in my spare time!
One of the ideas I had was crowdsourcing the data collection using a browser extension. My thought was that a Chrome extension could optionally scrape the results any searches that are done by FlyerTalkers (and anyone interested in the community), and then could present you with the option to submit it to a site that aggregates everyone's results. This could also help expose individual pricing changes, like differences based on status.
Just an idea for future expansion. The first step in that would be adding a form to let viewers submit observations manually, and then the browser extension could be built on top of that...
