The only downside of this extension business for me is that, had I known or suspected this was coming, I would have answered a couple of lucrative (but more time-consuming) surveys that came in late June: one for $10 and the other for $15. I didn't answer them for two reasons:
1. I've had difficulty getting the points for this type of survey to post (it promises posting in 5-7 business days, but that never happens) and
2. The points were set to expire in just a few weeks anyway, so it seemed like a complete waste of time to answer the surveys. And of course I could have redeemed the points on SOMETHING -- except that most of the redemption opportunities are just worthless for me. Only HHonors is really usable or worthwhile. (Maybe magmall would be too; haven't tried them yet.)
They really need to rethink this whole points expiration thing; having a policy that DISCOURAGES people from answering surveys because of the imminent expiration of the points that would be earned seems really counterproductive.
