Reducing margins, become about to cut simple deals with PC? (1-8)
I believe the answer is:
e-commerce
'deals with pc?' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
(Other definitions for e-commerce that I've seen before include "Internet trade" , "Transactions conducted on the internet" , "Online trading" , "Business conducted via the internet" .)
