I believe the answer is:

adams ale

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

'where large quantities of this drink might be bought cheaply?' is the definition.
'adams ale' can be an answer for 'drink' (I've seen this before). I am unsure of the rest of the definition.

'where large quantities of this drink' is the wordplay.
'where large quantities of' becomes 'adams' (I can't justify this - if you can you should give a lot more credence to this answer).
'this drink' becomes 'ale' (type of beer).
'adams'+'ale'='ADAMS ALE'

Can you help me to learn more?

(Other definitions for adams ale that I've seen before include "water instead" , "Water (humorous)" , "simple drink" , "Liquid refreshment" , "Drink - a sad meal (anag)" .)
