Download the Zogo app for iOS  or Android and register. Use invite code: AME9 to earn 300 pineapples(points).  Join the first pineapple party and participate in some trivia to earn more pineapples. Once you hit 5,000 you can get a Free $5 gift card to Amazon or other retailers, you’ll be able to do this pretty quickly. The earn rate seems to drop off pretty quick, so once you earn the $5 it might not be worth doing more.
