The Synchrony Bank store card is hands-down the shittiest card product I've ever used from any bank. I signed up for it and they screwed up my ACH multiple times, then closed my account, because they were running auto-debit ACH from a different address than command-debit ACH, and had no one who would explain this. (They bought something formerly used by Walmart, so when I saw a large Walmart debit I blocked it, as I never use my checking account there...) In Q4 2016 (I think) DiscoverIT was 5% on Amazon purchases, which is equally good, but then the Chase Prime Visa also became 5%, so there's no advantage to the Synchrony card whatsoever.
