Attention here. Blizzard Entertainment announced paid battletag changes available now. Read more details in the following parts. In addition, you can also get the lowest price Diablo 3 Items that can meet your requirements here.

Read the original post from the official site.
The BattleTag you originally chose doesn't have to be your nickname for all eternity—sometimes you want to switch to something more suited to the hero (or villain) you've become since you first arrived in the Blizzard universe. While we've always provided players with one free BattleTag change per account, now we're pleased to offer an additional paid BattleTag change service for those of you who would appreciate the opportunity to choose yet another new moniker.

Free First Change
If you're ready for something new and haven't already used your free BattleTag change, simply visit your Account Management Dashboard, and click the Change link under your Account Details to the right of your current tag.
If you haven't used your free change yet, don't worry—BattleTag changes don't expire and yours will be waiting for you if and when you ever decide to use it.

If you've already used your first free change and still feel like a new nickname would be a better fit, the option to purchase an additional change will be available within Account Management. Changes are available for $10 each, and your new moniker will be reflected on your friends list automatically after making the change.

Players can also check out Blizzard Entertainment support article or visit the Shop page for more details. BTW, don't be hesitated to buy Diablo 3 Items if you want to level up your characters. We guarantee 100% safe and cheap D3 Items with 5min delivery. BUY NOW!
