Great news for those eyeing very popular Nokia Lumia 521 in US. After selling out in matter of hours at Walmart and HSN post its launch, Lumia 521 is back in stock at HSN. Though pricing at HSN is higher at $149.95 compared to amazing Walmart pricing of $129.88. But, currently you can buy Lumia 521 only from HSN as it still is out of stock at Walmart both online and in store. HSN has rightly termed it as “Show stopper“. The retailer informs that Lumia 521 orders will ship on 16th May. Just hoping that Nokia keeps the show going by keeping it in stock!!
