These are great for those planning to use on a unlocked GSM phone on this carrier. For compatible GSM or CDMA phones, please checkout this link. - Discombobulated
Deal appears to be dead for SIM card only purchases. You can still get free overnight S/H if your total order is $45 or more, but not for just sims. Looks like the promo code was set up incorrectly and they caught on.
Straight Talk is offering free overnight shipping for SIM cards (nano, micro, and full sized) until 12/19/14.
I am getting the Amazon Fire Phone and am already a ST customer but need a nano-SIM. The option for free shipping lists as FREE overnight sgipping - $14.99 in the drop-down of options, but a coupon code is applied after you provide billing info. I purchased two.
In my area (northern New England) both T-Mo and AT&T cards work, but AT&T is better coverage.
