If replacement/backup batteries for your HTC Thunderbolt were something of interest to you then heading over to Verizon’s accessory site immediately would be a good idea. The official OEM standard battery can be had for $19.99 after a mysterious “additional discount” has been automatically applied by their checkout system. So yeah, you don’t need a coupon code or anything special. All you have to do is add the $39.99 standard battery to your cart and once you check out it should show up as $19.99.
Buy.
