I was skeptical
I was skeptical, but having the time, I tried it anyway. It takes me about 40 days to get a $250 reward. The experience wasn't too bad, but the 30 days rule wasn't clear for me, so, when I was 1 offer short to get a $500 reward, the first deal had expired. So, you have 30 days to finish all deals to get the reward you're looking for. You need to provide a valid ID, and to wait a few days for the offer verification. If everything clears, you'll get the reward.
