Possibly. It probably just slipped through (it's actually Foot Locker that makes those rules and checks if the orders are valid/eligible for cash back... then, it gives Ebates the cash back... which Ebates then gives to you).
That's why I said that you "run the risk of not getting cash back"... sometimes it may still go through, but most of the time they will catch it.
I literally got 9 cash backs by using the "Where's my Cash Back" feature in just 1 day.

I really think that they don't give it out automatically on purpose, so they can keep the cash in case you forgot.
You really have to "remind" them about it. As if they don't know...
Nevertheless, I'm thankful.
