Dash across shopping area seeing such conditions (5,5)
I believe the answer is:
small print
'such conditions' is the definition.
(terms and conditions)
'dash across shopping area' is the wordplay.
'dash' becomes 'sprint' (synonyms).
'across' indicates putting letters inside.
'shopping area' becomes 'mall' (shopping mall).
'sprint' enclosing 'mall' is 'SMALL PRINT'.
'seeing' acts as a link.
(Other definitions for small print that I've seen before include "Obscure terms" , "You may regret not reading this!" , "Words often ignored" , "Be careful to read this" , "Inconspicuous part of agreement" .)
