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.
