ch-chang 

To charge an extraneous amount of money on a transaction for the sheer fact that it is possible.

(Derives from the onomatopoeic sound of a cash register opening)

Person 1: I found a buyer for my old car!
Person 2: Really? Are you gonna ch-chang him?
Person 1: You better believe it.

what may change you, but you can't trace time (courtesy of Bowie)

Ch-ch-ch-ch-Changes
(Turn and face the strain)
Ch-ch-Changes
Don't tell t hem to grow up and out of it
Ch-ch-ch-ch-Changes
(Turn and face the strain)
Ch-ch-Changes
Where's your shame
You've left us up to our necks in it
Time may change me
But you can't trace time
