As you probably know (if you follow me on facebook), I recently converted from a blackberry to a thunderbolt (android). The thunder bolt is great but it uses up tons of power to operate. I've been through all the power saving tricks. In short, I needed to buy another battery. So I went to the store and they wanted to charge me $50 for a battery on a phone that retails for $600. I guess they think if you can buy a phone for that much you have $50 more for an extra battery.
They will ship it directly to you by usps or fedex. I would suggest using fedex you will recieve it in 2 or 3 days. USPS is slow and took about a week. Again check out cellphoneshop.net Let me know what you think of it or if you already know about them.
