What is the going rate that Apple charges merchants in the US for their service? Wallmart is keen to offer the best possible deals, asks for best possible prices from their partners (suppliers). Dont you think that by agreeing to the allegedly high % that Apple charges, it goes against their princple? I think that if Apple wants its Pay to be accepted to Wallmart to either give it for free or even pay for it, because Wallmart adds value to their offering, not vice versa!
