Am not impressed with E-rewards since enrolling with them approx. 18 months ago. To date I've only managed 15.90 in my account and get so few that I've almost closed my account a few times. I am on AOL, but on one of the older versions so still receive them fine. On average I receive only 1 every 2 months or so. And yes, I did change all my preferences to get the most.
Also thought I remember Marriott Rewards being one redemption option, but as of today, it's not listed. Once I do hit my 25.00 reward level, I'll get my 1K HH points, close my account and bid good ridance to this turkey of a program. Imagine reading & responding to all those emails for 1K HH points!
