Chaps surer to go wrong as those looking for a deal maybe (10)

I believe the answer is:

purchasers

'those looking for a deal maybe' is the definition.

'chaps surer to go wrong' is the wordplay.
'to go wrong' indicates anagramming the letters.
'chaps'+'surer'='chapssurer'
'chapssurer' with letters rearranged gives 'PURCHASERS'.

'as' is the link.

I've seen this clue in The Telegraph.
