Paying by card

After placing your order, enter your card details on its secure payment page. Placing the order does not charge your card. Your card number goes directly to the payment processor. After an approved payment, your order page shows the payment status.

If checkout reports a problem, read the message before trying again. If you are unsure whether payment went through, check your order page or contact support with your order number.

An unfamiliar statement description can be checked against the payment details above. Contact support if you cannot match a charge to an order.

Paying by bank transfer

After you place the order, its payment page shows the recipient, amount, and reference to include. Use those details exactly so we can match the payment to your order.

Your order stays awaiting payment until the transfer is received and confirmed. Unpaid orders are cancelled after 72 hours. Follow the deadline and instructions on your order page.

If you entered the wrong reference, sent a different amount, or need help with the deadline, contact support with your order number and the date and amount sent.

Paying with Bitcoin or Lightning

Your order opens a payment invoice with an address or payment request. Use the amount and network shown on that invoice, and check them before confirming in your wallet. Cryptocurrency transfers cannot be reversed once sent.

Lightning and on-chain payments confirm at different speeds. Your order updates after the invoice confirms; the timing above explains what to expect.

If an invoice expires or shows an underpayment or overpayment, contact support with your order number and invoice ID before sending another payment. Follow the invoice instructions rather than reusing an expired address or amount.

After payment

Keep your order confirmation email. It links to your order page, where you can check payment and shipping status. Returning customers can also find their orders in Account.

Review the Terms of sale, Shipping, and Returns policies before ordering. Our Privacy Policy explains how order and payment information is handled.

Refund methods and posting estimates are explained in Returns. Contacting support does not waive your payment dispute rights or extend your provider's deadlines. Use the descriptor shown for your payment method to recognize a transaction; a billing descriptor is not a promise of anonymous payment.

Need help with a payment?

Send us your order number and a short description of the issue. Never send your full card number or wallet keys.
