 // Remove selected payment method on page onload
            initialize: function () {
                var deferred = $.Deferred();

                //Remove selected payment method from quote
                quote.setPaymentMethod(null);
                //Remove selected payment method from localstorage
                checkoutData.setSelectedPaymentMethod(null);
                //Refresh payment section
                getPaymentInformation(deferred);

                var self = this;
                this._super();
            },
