The lower rate I found was $13 less than my orbitz reservation. Instead of adjusting the rate, they added 13 orbucks to me reward, so I received a total of $63 orbucks. I did, however, have to contact them to see where they were. They replied back and my orbucks were added to my account immediately. This was back in February. The time frame may have changed, but I remember it being 14 days when I did it.
