Actually, the one that makes sense for a competing bid would be Wesfarmers.
They have their focus on the API deal, but I'm sure they could manage two deals at one.
With Coles off their books, this would be another online D2C play that they could put in with Catch.
Youfoodz would let them build out a D2C groceries business and combine it with the Catch delivery network.
Must be a few Investment bankers out there today on the phones looking for alternative bids, Wesfarmers should be top of their list.
