I need to pay for an application which (i) requires exact payment and (ii) payment in RMB.
I can't figure out a way to get 42 RMB exactly (the lowest denomination my bank had were 100 RMB notes).
If anyone has 42 RMB kicking around and can meet in Wanchai, I'll swap you a 100 RMB note for exactly 42 RMB.
