Reportedly purchase most of the food easily (2,3)
I believe the answer is:
by far
'easily' is the definition.
(I've seen this before)
'reportedly purchase most of the food' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'purchase' becomes 'buy' (buy is a kind of purchase).
'most of' means to remove the last letter.
'the food' becomes 'fare' (fare is a kind of food).
'buy' is a homophone of 'by'.
'fare' with its last letter taken away is 'far'.
'by'+'far'='BY FAR'
(Other definitions for by far that I've seen before include "easily" , "To a superlative extent" , "Very much" .)
