So I just got this e-mail from United asking if I wanted to sign up for E-Rewards, which allows me to earn "dollars" toward rewards on United, Hertz, Blockbuster, Vail Resorts, etc. I had to fill out a lengthy (and I mean lengthy) questionnaire so I could receive my free gift. What's the free gift? A free rental at Blockbuster (with the purchase of a rental). Not much of a gift! But hopefully this will be another way for me to get additional travel treats on United. We'll see.
