P14: 300 or 600 free United miles by joining Opinion Miles Club [Miles, Airlines,Freebies]

By following this sign-up link, you can join Opinion Miles Club, spend about 20-30 minutes to fill out a profile and complete a survey, and receive 300 or 600 MileagePlus miles credited to your account. When I went through the process, though it initially offered 600 miles, I only received 300, but for 20 minutes of your time it’s probably still worth it especially if you are trying to top off your Chase Ink Bold sign-up bonus.
