Yesterday, we received a tip from a Windows Central reader that the Lumia 640 from T-Mobile would go on sale in Walmart stores on June 20. Now that same tipster, Twitter user "@sedp23", is reporting that he has now purchased that phone from his Walmart location in Chicago.
The images show the opened and working Lumia 640 in our tipster's hands. Earlier today, T-Mobile finally put the Lumia 640 on sale on its website for the full retail price of $129.84
It's likely that other Walmart stores are also selling the Lumia 640 right now but it's best to call ahead to your location store to see if they have the phone in stock.
Thanks for the tip @sedp23!
