Review before payment
At checkout, confirm your products, quantities, delivery address, shipping option and final total before submitting payment.
Payment methods
Available payment methods can vary based on your location, currency, order and current payment configuration. Use only the payment options displayed on the secure GradeZO checkout.
Payment problems
If a payment fails, first verify the billing information and try an available alternative method. Do not send card numbers, security codes or passwords to support.
Order confirmation
After a successful order, retain the confirmation details. If money was debited but an order confirmation was not received, contact support with the transaction context without exposing sensitive payment credentials.
