Now, a report reveals that Walmart stores are beginning to gear up for its sale on T-Mobile. Even better, the well spec'd (and reviewed ) phone looks to be grabbing a favorable $99 price point.

The Microsoft Lumia 640 is getting a very slow rollout in the United States. So far, only Cricket has the device available despite AT&T and T-Mobile on the roster for eventually carrying the device.

Reader of the site Mark Dunn sent in the above photo showing the SKU label and pricing for the Lumia 640. He notes "2 came in, and they sold fast" although it is not 100 percent certain the phones have yet been stocked. The phone and SKU were spotted at a Walmart in Rochester, New York.

Regardless, we expect T-Mobile to begin selling the device in the coming weeks. It is unclear if the T-Mobile variant will support Wi-Fi calling, a coveted feature that often holds up device approval before sales begin.

Anyone else see a T-Mobile Lumia 640 at their local Walmart? Let us know in comments or jump into our Lumia 640 forums for more discussion.

Thanks, Mark, for the tip!
