Keep in mind that AGR points were "re-valued" last spring ahead of any announcement of a new/revised AGR program.
The purchase cost of points went from $0.275 to the current $0.0377 per point (before bonus). They did increase the annual purchase maximum from 10,000 to 15,000.
This event created a lot of discussion here on AU and Flyer Talk about whether it was still worthwhile buying points every year.
When this point re-valuation occurred, most of us had no knowledge of a revised AGR program which will take effect in a couple of weeks.
