hi, this is indeed a good function…good job and thanks.
but as i was using it, i wonder if it can be “upgraded”…ie
while going through the best miles card to use for toastbox, i realize i do not have all the cards stated, however i managed to earn miles by using grabpay (with points that can convert to miles) and top up grabpay with Amex krisflyer card.
my point is apart from just cc directly, maybe offer an alternative method that can still earn miles/cashback (sometime the alternative/combination method results in better returns, in this case, grabpay topup by Amex has a promo).
just a random suggestion.
if this is already available, kindly guide me.
