The headline 20.88% is an effective combined saving for Citi Cash Back Card members who also use Shell GO+. It is not a single pump discount: 10% comes from GO+, 4% is an instant Citi discount and the 8% card cashback is calculated after those discounts.
A separate gift mechanic rewards S$200 in gross fuel spend with a three-bottle box of Kim’s Bird’s Nest Beverage, capped at two redemptions per cardmember while stocks last.
