Improvement in supplies of Lumia 521 has brought it back at HSN after T-Mobile, where the prepaid Lumia 521 sold out just after becoming available. The device had been out of stock at HSN for quite long this time around. Anyways, compared to T-Mobile pricing of $199 for No-contract, HSN is still selling Lumia 521 for $50 less at $149.99. Just hoping supplies are consistent and demand converts into substantial volume in Q2.
