at a discount

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

'how things' is the definition.
I know nothing about this answer so I can't tell whether this works.

'be bought for cash' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'count' (counting is a kind of being) and 'count' is present in the answer.
This explanation may well be incorrect...

'may' is the link.
