Your TPT credits are shown in U.S. Dollar (USD) amounts as part of your account balance.
To apply your account balance (which includes TPT credits and TPT ClassFund contributions, if applicable) to a purchase, select the "Use account balance” option under the "Secure Checkout" button in your cart. Then, enter the amount you'd like to apply toward your order, and click "Apply." Your receipt will show the amount used listed as “Account Balance.”
Your account balance is the sum of your TPT Credits and any TPT ClassFund contributions that have been given to you.
You can check your account balance for a breakdown of TPT Credits earned and TPT ClassFund contributions. Just select "Account Balance" from the header dropdown menu.
