walmart like all the other biggies need to convince consumers to use their own in house branded credit card much like CT and Loblaws do every time you  line up at the register

they could do this by offering bigger incentives  for switching  - if the fees to VISA and the like are 100 million per annum - Walmart has a huge reason  to  lure the consumer away from VISA

I suspect this truce  is merely  a lull in  a long term battle
