Note that people can end up getting slightly different e-Rewards redemption options for no reason why anyone can figure out. example- For a long time, some folks could redeem $100 for 7K Hhonors points while others got stuck with a worse rate , and us in the e-Rewards thread in SPAM (come over there for lots of program discussion) could never quite find a definite pattern. I've also got Iberia Avios for 3,000 per $100 and I think others only get 2K for the same $100.

e-Rewards oddity #2- even though IHG cut back on what counts as a status point for 2013, at least this year PC points through e-rewards still count toward gold/platinum status.

e-Rewards gives you the best bang for your buck at a least 100 miles or better per $5 survey, but if you've got more time than money you can rack up more miles per month at Opinion Miles Club.

Harris Rewards is even worse in terms of redemption rates- 800 points= 200 miles for Delta or US Air, so a 100 point survey from them is only 25 miles. (But since Delta pulled out of e-Rewards, I'll take my sky pesos where I can find them)

I did my first cashout from Peanut Labs via points.com over the weekend, and will report back when they let me know how many miles/points I can get per 100 'units'.
