I will bring any legal goods that fits my cabin bag. For liquid related goods, I will only buy if I can find it in Changi Airport. Charging fee will depend on the goods price, size & delivery location. Of course the fee is negotiable :) Will use klikbca exchange rate for SGD -> IDR.
I prefer to meet at Soekarno Hatta Airport, Jakarta to handover the goods.
Otherwise I can use courier service JNE to send the goods. Please note, JNE delivery fee to be paid by you.
Happy shopping ^_^
