MetroPCS Messager and MyShot Discounts

If you're planning on buying a MetroPCS phone before January 10th, take a serious look at the Samsung MyShot and/or the Messager. The reason: you get cash back for buying. If you buy one phone, you get a $25 Visa gift card back. Two or three phones net you a $50 gift card. Four phones get you a free fifth phone, after a mail-in rebate. The MyShot and Messager are higher on the price scale, at $139 and $199, respectively, however if you want to outfit a family with the phones, the end price of $111 or $159 sounds a bit more attractive...
