Some people that applied for the Blue Cash Preferred card in late August will have their first year annual fee ($95) waived due to the fact that the American Express didn’t properly display the annual fee on their website. If you’ve already had the annual fee charged to your account, they will issue a statement credit to refund the fee amount.
I suspect this had something to do with the fact that American Express increased the annual fee on this card to $95 (from $75) on August 3rd. The reports I saw on /r/churning said that they had applied on or around August 26th, 2016 so I suspect this will only affect a very small number of readers, but could help explain why you have received a statement credit for $95.
