Sort of deal cards on time (7)
I believe the answer is:
package
'sort of deal' is the definition.
(package deal)
'cards on time' is the wordplay.
'cards' becomes 'pack'.
'on' is a charade indicator (letters next to each other).
'time' becomes 'age' (age is a kind of time).
'pack'+'age'='PACKAGE'
(Other definitions for package that I've seen before include "Collected programs" , "Type of holiday" , "Parcel or bundle as for posting" , "Wrap, put in a box" , "Put into a box/wrapping" .)
