I've been ignoring their survey invitations but got bored just now and decided to complete one. I did so and got these 10 tickets where I could enter in sweepstakes for gift cards and cash. Has anyone won anything in this survey panel? It was a very quick survey so I was like "Wow, I have nothing to lose."
