While loot boxes are gained automatically at each level, you can purchase them if you'd like an extra chance at that skin or emote you have your eye on.
You can purchase Loot Boxes in the game by selecting Loot Box from the main menu and clicking Shop. Choose the number of boxes you would like to purchase, select your payment method from the dropdown, and click Pay Now. You may be prompted for your Blizzard password.
Loot Boxes are also available for purchase from the Blizzard Shop.Note: All Loot Box purchases are final.
Overwatch™ uses your Blizzard account's primary payment method (credit card or PayPal™) to complete purchases. If you do not have a credit card or PayPal account on file, you can add them on your Blizzard Account Management page.Add Payment Method
If you do not have access to a credit card or PayPal, Overwatch also accepts alternate payment methods like prepaid cards through Blizzard Balance. If you choose to use Blizzard Balance, it must be loaded on your account before you can use it to buy Loot Boxes.
If you have Blizzard Balance on your account to cover the price—including sales tax—Overwatch will try using it before trying your primary payment method.Load Balance
Note: Loading Blizzard Balance takes up to three days to complete. For a more immediate payment source, set up a primary payment method instead.
