I went to reBoost through callingmart.com and my order was cancelled and refunded minutes after it was placed. I called them on the phone to find out why. I was told that "Boost" no longer would accept re-boosts from vendors on the internet. They were no longer selling Boost - re-boosts. She said you would have to have a re-boost card in hand and enter the info to get a refill now. She told me this became effective today 12/31/11.
As per usual I got whacked with taxes and fees for my reboost that I had been lucky enough to avoid paying for the last three years. Guess all we do is wait for people to post any cards that go on sale or buy cards on eBay again. Remember you need the card in hand or at least the numbers to get the refill. No one can refill your account for you unless they pay by credit/debit card. I am still trying to locate anything about this on the Boost website but no luck as of yet.
I found a great website that offers huge discount on Boost Mobile and Virgin Mobile. I have already used it a couple times and they seem pretty quick to refill. Only bad part, I did one refill at night and apparently they only process during business hours. The Web Site is boostmobilesav.com
Anyways, I refilled the $55 Boost refill for only $52.95, and the $50 refill for only $47.77. Some pretty good savings if you are like me and have to pay state tax and 911 tax, which they don't charge.
