This one really speaks volumes about sales volume of Lumia 521 at HSN. It is not only best seller phone at HSN but also the 2nd best-selling electronics item. This is huge as there are many cheap electronic items which may be sold in thousands in one day at HSN. Lumia 521 and Lumia 520 may really make the Q3 biggest ever for Nokia in US.
Thanks Ruchiro for the Tip!!
