Some devices start very strong and disappoint later in terms of sales, while some start steady and strong and just get stronger with time. Same is the case with Lumia 928 which obviously started well at Verizon but not that well at Amazon. One reason behind that was also Black model being out of stock for very long. No after being back in stock it has climbed to 5th and now 6th top selling rank at Amazon. But, here comes not so good news. It has again sold out and is out of stock now along with the White.
