The Coolpad Arise is now $14.99 through 3/29/15, or $12.00 via Kroger digital coupon for 20% off i-wireless phones (exp. 2/28/15). The LG Optimus Fuel is $29.99 or $19.99 via Kroger digital coupon for $10 off Tracfone/Net10 phones.
Be wary of the Coolpad - see the wiki for info on a potential backdoor.
UPDATE 12/12/14: The $9.99 sale on the Coolpad Arise has been extended through 1/6/2015. There was no tag on the LG, so I'm not sure if that has also been extended, but it did have a tag saying any Tracfone or Net10 phone purchase would receive 500 gas points.
Update 12/18/14: User Geraldism reports the LG is ringing up at $19.99.
ALSO AVAILABLE: Motorola Photon Q (full QWERTY keyboard phone, i-wireless) for $39.99.
Kroger is having a sale on prepaid Android phones. Both of the below phones are $9.99 with a Kroger Plus card through 12/9/14.
You don't have to activate cell service, so these are $10 Wi-Fi Androids to use for whatever you want - apps, Web browsing, MP3 player, etc.
Note - They also earn bonus fuel points; I got 4x but others have reported more. Not sure how long that part of the deal will last.
Note 2 - Not all stores are advertising the deal, but both phones should ring up at $9.99.
Note 3 - Some people are reporting credits from Tracfone or i-wireless upon purchase. YMMV.
