(pseudo-edit while typing) I think I found it: http://cl.ly/0d3r3F1343132g131y36 (notice down at the bottom) though all the 'learn more' links just take me to the essentially-useless help home-page, rather than to a place where I could actually learn more.
What do you get if you go to my first link? Might there be time to grandfather in a better plan?
Actual edit: woah - it just started redirecting me to the more expensive option (hasn't been for the past 1/2 hour). wtf.
