Also, I've seen offers that apparently have been extended. In multiple cases, I've added an offer but later noticed that the same offer has a later expiration date and has a check mark indicating that I've added it. I assume that, in such a case, I would not receive the credit again if I met the conditions again. (Since I just learned how to look at Redeemed offers, I have no idea whether they appeared there.) I'd be delighted to learn that an offer extension includes the offer's re-issuance.
