I usually like E-Rewards. I just redeemed $100 for Choice Privileges, which I will redeem for WN RR points. This will be the second time I have done this. First time was in order to top up my WN account for a free reward flight.

Now if you were to ask me about Opinion Outpost, that is another story. i just cancelled my membership, as I never qualify, after spending way too much time answering questions, only to be told I am not a good candidate.
