Republic Wireless offers the Motorola Defy XT for Republic Wireless together with a $50 Google Play Credit for $99 when you choose the $29/month unlimited plan. With $10 for shipping, and assuming you use the gift card, that's the lowest total price we could find for this phone, on any pay-as-you-go carrier, by $141. This hybrid cell phone makes calls over WiFi (but can also use Sprint's 3G network, too) and features a 1GHz processor, 3.7" touchscreen LCD, Bluetooth, GPS, and Android OS 2.3 (Gingerbread). Deal ends March 18.

Of note, if you select the $19/month unlimited plan, the price of the phone is $249, a price low for this phone on this carrier.
