Yes and no.  They use the rewards as a tactic to reel you in to using the service.  It is a great reason to order through them of course.  If spending thousands of dollars on the promise of rewards dollar coming your way and they fail to meet that obligation, it is an issue.  I know, free money, but its a part of the reason I went the route of ordering through them.  I guess we will see how it plays out.  But it does seem very fishy to me.
