MetroPCS, the prepaid wireless provider that's operated by T-Mobile, is currently offering the Lumia 521 for $19 in its retail stores. This is perhaps the cheapest price we have seen for this variant of the highly popular Lumia 520.
The phone was also on sale on the MetroPCS web site at that same price earlier today but it looks like it has sold out of its online inventory at the moment, but if you go to your local MetroPCS store you can get the Lumia 521 for $19. There is apparently no catch to this deal. You won't get that price via a rebate that shows up months from now; it's a plain and simple price reduction.
Just a reminder: The 4-inch Lumia 521 has a 1 GHz dual-core Qualcomm Snapdragon processor, 512 MB of RAM, 8 GB of onboard storage, and a five megapixel rear camera. Do you plan to head over to your nearly MetroPCS store to get this Windows Phone 8 device?
