do you not realize that Amazon is much much more than Walmart has or possibly ever can be? not only is their online market place KILLING IT but they have their hands heavily in the tech sector. AWS and their HUGE Agency contract (among many other wealthy private sector clients), many successful proprietary products (echo, fire, streaming movies on demand, etc).
Obviously getting TBEV in Walmart will be huge for TBEV but don't compare Walmart (69.54) to Amazon (760.59), they aren't even in the same league.
