Made available to every purse, no matter what the difficulty (2,3,5)
I believe the answer is:
at all costs
'made available to' is the definition.
I can't judge whether this definition defines the answer.
'every purse no matter what the difficulty' is the wordplay.
I cannot really understand how this works, but
'every' could be 'all' (similar in meaning) and 'all' is present in the answer.
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
'matter' could be 'tc' (Tc is an example) and 'tc' is present in the remaining letters.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
The remaining letters 'ass' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for at all costs that I've seen before include "no matter what the consequences may be" , "Regardless of the price" , "Regardless of expense" , "Whatever the consequences" , "Regardless of the sacrifice involved" .)
