Just to let everyone know, I added an airtime card for my mom's phone to me (a 60-minute card) and it extended her expiration date by 90 days. So the new card values are really here now, and promo codes work great. I added via the web and, if anything, promo codes have gotten a tad better. Granted, they're one-time-use only but I was able to double the airtime relative to the card's face value with promo code 51283. Then again, rumor has it that most of these promo codes are going to expire on the 15th...who knows?
But anyway, the new Tracfone revolution is revving up...and it's great for everyone!
