The going price? (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
fare
'the going price?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for fare that I've seen before include "Get on - passenger - provisions" , "Taxi charge; food" , "Charge for travelling on train or bus" , "going rate?" , "Amount charged" .)
