Quick head-up. Lumia 521 is now in stock at Walmart. The pricing is awesome at $129 and it is really hard to grab this device at such amazing price, because of very frequent stock-outs. HSN has sold Lumia 521 at $129 for one day but rolled back the price to $149. So, it is Walmart once again where you can get it for $129 and let us hope this time the stock is enough.
