It's pretty weird that both Walmart and Best Buy will probably be required to advertise Apple Pay and yet won't support it at their registers that is going to burn a lot of customers. If they don't want to support the NFC payment movement they shouldn't sell the products that have NFC. They are just going to regret this decision at some point when NFC is the norm and they have to do yet another round of POS upgrades.
The phones doe a lot more than NFC payments. Why shouldn't they take a customers money just because they're betting that NFC payments will never achieve widespread popularity.
