Nexus 5 can run you $50 on Sprint, but only if you switch

The instant savings amount to $350, of which, however, a Benjamin is applied if you bring your number from another carrier, with the current Switch&Save promotion. Thus the actual price with a two-year contract extension is $150 for the handset, which doesn't differ all that much from the other flagships on Sprint, such as the Galaxy S4, which will run you $200, or $100 with the Switch&Save in its turn.

Overall, this confirms that the best place to get a Nexus 5 is from the Play Store, as Google is subsidizing the handset, or perhaps selling it at cost, to the tune of at least $50 (or euros and pounds on the Old Continent), making its own offering rather sticky and irresistible.
