Caller wasted time on charge for use of storehouse (9)

Ross

I believe the answer is:

cellarage

I'm a little stuck... Click here to teach me more about this clue!

'charge for use of storehouse' is the definition.
I can't tell whether this definition defines the answer.

'caller wasted time on' is the wordplay.
'wasted' indicates an anagram.
'time' becomes 'age' (an age is a period of time).
'on' means one lot of letters go next to another.
'caller' with letters rearranged gives 'cellar'.
'cellar'+'age'='CELLARAGE'

Can you help me to learn more?

(Other definitions for cellarage that I've seen before include "payment for port's security?" , "Charge for storing (wine?)" , "Stores" , "Cost of storing wine" .)
