Turn up without car on eastern sector of Amazon? (1-8)
I believe the answer is:
e-commerce
'sector of amazon?' is the definition.
(sector which Amazon operates in)
'turn up without car on eastern' is the wordplay.
'turn up' becomes 'come' (both can mean to arrive).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'car' becomes 'merc' (short for Mercedes).
'on' means one lot of letters go next to another.
'eastern' becomes 'e'.
'come' enclosing 'merc' is 'commerce'.
'commerce' put after 'e' is 'E-COMMERCE'.
(Other definitions for e-commerce that I've seen before include "Business conducted via the internet" , "Online trading" , "Transactions conducted on the internet" , "Internet trade" .)
