Rebate is accrued, but not given to you till later
The way I read it is that you don't get your 5% rebate credited onto your credit card for Meal # 1, until you go and qulaify for another iDine rebate for Meal # 2. But you don't actually get the Meal # 2 rebate, until you go to another iDine particpant restaurant and eat Meal # 3. Etc...
