Standard PS4 no longer available online at GameStop
Interesting enough, there are other PS4 bundles still available on the site. These are usually the same PS4 console but with a launch game added to the mix.
It's worth noting that the standard PS4 could still be available at your local store, but I suggest you hurry over and pre-order if you plan on doing so. It's clear that stocks are now limited. If not, the standard PS4 is still available on Amazon for three cents cheaper.
