Yesterday we informed how in stock Lumia 521 is top seller No-contract phone at Amazon.
Now seems supplies have really improved as it is in stock at Walmart too :P. And, it is now taking the best seller charts by storm. It is currently the no. 1 best seller phone at Walmart as well. That’s certainly very very impressive and it has happened for the first time when Lumia 521 has become the top seller at both Walmart and Amazon. it seems after Q2, Q3 will also see Lumia 520/521 contributing a lot to the overall Lumia shipments.
