What's the best way to pay Simpl Pay Later Bill (ANY BEST WAY TO SAVE MONEY ON PAY PAY LATER BILLS?)

today I will be paying Simpl Pay Later's Bill, BNPL service pay pending bill, and I was wondering if there is any best way or better way to pay the bill to kind of get cash back or discount on it. 

Please let me know :)
