the place i would check while in bangkok is panthip plaza. any taxi will know where/what it is. that is probably the only place that may have it. the likelihood that they will have it might be a little slim. however, just experiencing the plaza/mall is an adventure in itself so it may be worth the cab ride. it is not too far from the main shopping area of bangkok, you can even ask the skytrain workers what stop to get off at that's closest to panthip. it is walking distance, but not that close. if you are adventurous take the motorcycle taxi. they will get you there from the train station to the plaza 5x faster and cheaper, but its a little bit more dangerous haha.
