As part of the Cyber Monday 2015 sale, AT&T’s subsidiary Cricket Wireless is now offering Samsung’s Galaxy S lineup of devices with 50 percent discount. However, this is a limited period offer.

Cricket Wireless’ Samsung Galaxy S4, Galaxy S5 and the latest flagship Galaxy S6 have been listed for just $99.99, $199.99 and $249.99, respectively. The original price of the devices is $199.99, $399.99 and $499.99 for S4, S5 and S6, respectively.

This Cyber Monday sale started on Nov. 30 and it is valid through Dec. 3. However, it goes without saying that the carrier will accept the orders only until the stocks last. Potential buyers can avail this promotional offer “with activation on a smartphone plan.” This offer is apparently valid for both existing and new customers of Cricket Wireless. In addition, the carrier is also offering “$100 Cricket Shopping Card” for those planning to switch to Cricket by Dec. 6.

Furthermore, the Cyber Monday 2015 deals also include the following devices: Samsung Galaxy Grand Prime, LG G Stylo, ZTE Overture 2, LG Risio, Motorola Moto E and Nokia Lumia 635. The Galaxy Prime can be purchased for $29.99 after a $50 mail-in rebate via Cricket Visa Promotion Card and $20 instant discount. The original price of the device is $99.

The LG G Stylo, on the other hand, will set the buyers back by $49.99 after a $50 mail-in rebate via Cricket Visa Promotion Card and $50 instant discount. The original price of this LG device is $149.99.

The rest of the aforementioned devices from ZTE, LG, Motorola and Nokia can be availed for free after $40, $30, $50, $20 mail-in rebates, respectively. The data plan under Cricket starts at $35 per month, after availing $5 Auto Pay credit.
