I know some have posted here saying it might be too late to sign up for e-rewards and accumulate enough ($25) to do the minimum transfer. I signed up in mid-August and I'm already up to $15 and change. Of course there's no guarantee you'll get enough, but if you fill out all the info and ask for as many surveys as possible, and importantly, have them email you notification when surveys are available so you can do them quickly, I think it's very doable to work up to $25 in the time left (over 2 months).

But YMMV. It would suck to work up to $24 and be waiting for that last survey in the final days of GS 2011.
