When redeeming two separate codes for the same value of Minecoins in a row, you might receive the ‘you already own this product’ error. If that’s the case, follow these steps to solve the issue:
- Redeem your first code in your Microsoft account or on Minecraft.net.
- Launch Minecraft and visit the Marketplace before redeeming the second code.
- View your Minecoin balance in the Marketplace and verify the Minecoins were added to your account.
- Return to the Redeem page and enter the second code.
