Try to get free perhaps? (3,3)

I believe the answer is:

ask for

I'm a little stuck... Click here to teach me more about this clue!

'get free perhaps?' is the definition.
I can't judge whether this defines the answer.

'try to' is the wordplay.
'try' becomes 'ask' (I can't justify this - if you can you should believe this answer much more).
'to' becomes 'for'.
'ask'+'for'='ASK FOR'

Can you help me to learn more?

(Other definitions for ask for that I've seen before include "Make a request" , "Demand" .)

I've seen this clue in the Evening Standard.
