Just received this in my email. Considering the number of Black Friday and Cyber Monday deals flying around this shouldn't be hard to reach for the bonus points. The other good feature is you don't need to click through the FlyBuys page any more to get your points, so this shouldn't break any Cashrewards click-throughs. There's a reasonable list of exclusions, though.
