The price of company on the street (4)
I believe the answer is:
cost
'the price' is the definition.
('cost' can be a synonym of 'price')
'company on the street' is the wordplay.
'company' becomes 'co' (abbreviation).
'on' says to put letters next to each other.
'the street' becomes 'st' (abbreviation).
'co'+'st'='COST'
'of' is the link.
(Other definitions for cost that I've seen before include "Fee" , "Amount to pay" , "Total spent for goods or services" , "Outlay required to buy" , "Estimate the expense of doing" .)
