Well-Trained Mind Press can process orders using ClassWallet. However, ClassWallet's practices vary from district to district and state to state, and you need to work within the guidelines specific to your district/state's ClassWallet.
Check with your ClassWallet Help Center to learn the processes set up by your district/state.
If WTMP is not yet a vendor for ClassWallet in your district, email support@welltrainedmind.com and let us know. We will do what we can to help.
