[SafeSituation]

As of 3:15 EST, the 16GB version switches from "Sold out" to "Add to cart" about once every two refreshes. Even when it's "in stock", adding it to your cart triggers an error.

The 8GB seems to be consistently in stock, advertising a 4-5 week shipping period. It is possible to add this one to your cart consistently.

EDIT: Now getting a generic Google server error page: "We're sorry, there was an error. Please try again later."
