Like I said, my information is spotty, but good to know, thanks. Looks like they also have pro-rated bundles (at the same time or later, I can't discern).
However, a search suggests that this feature was announced 2 years ago next month. Which is one of those grey areas where advertisers say "hundreds" and the potential customer thinks, "347" whereas the advertiser means "147".
So, you're right, and thank you for the update, but also I'm keeping an eye on you...
