The answer is clearly not enough judging by the fact that they are going to concentrate on higher return businesses. Coles has allot of goodwill and WES have redirected allot of capital into it to prop it up. Remember Ian McLeod would always remind investors about how poorly Fletcher's crew left the place when they handed the keys over to WES, with stores looknig woeful in some cases. So WES have spent allot of money getting up to a certain standard to compete with WOW.
I am thankful that the experiment is over as a long time WES owner.
