Tip 1: This section has the largest point values available, this is because you have to submit credit card information. Be sure to read carefully on the actual offers page because you can get TONS of points if you do it right!
Tip 2: Keep in mind, something that would charge you $4.99 for a trial membership could get you 2000 points which equals $20. So you could essentially pay the $5 in order to get $20, then simply cancel your account so you don't get recurring billing! =)
