Where to buy lady finger in Bintaro?

Okay, I've had enough. I'm dying to make another Tiramisu this weekend. But I can't find any store near Bintaro that sell lady fingers. No, I'm not tolerating. I don't replace lady fingers with sponge cake. The texture and taste is different. This is frustrating. Should go all the way to Fatmawati through a crazy traffic jam just to buy the lady fingers, 2 hours alone, I'm roughly calculating. God help me T.T
