@mistercheap I’ve gotten credit on both. How would each know? In fact, I’ve quadruple dipped before - Kroger cash back, Ibotta, coupons.com and Alexa.
But sometimes coupons.com will reject it if it was sale (but not always), but Amazon always accepts it no matter what. Even if I added the offer after buying. There’s slim pickings on both, but I’ve used it several times now.
