Checkout & Billing

Payment Information

Derlune™ aims to keep checkout clear and straightforward. This page explains the payment options that may be available when you place an order, how payment authorization works, the currency used for purchases, and where to seek assistance if a transaction cannot be completed.

$

USD Checkout

Store purchases are presented and processed in United States Dollars unless otherwise shown at checkout.

▣

Payment Options

Available payment methods are displayed directly during the checkout process.

✓

Clear Billing Support

Our customer service team can assist with general order and payment-related questions.

01

Payment Currency

Purchases on Derlune™ are processed in United States Dollars (USD), unless another currency is specifically displayed during checkout.

If your card or payment account uses another currency, your financial institution or payment provider may convert the transaction according to its own exchange rate and policies.

Currency conversion fees, foreign transaction charges, or other bank-imposed fees may be determined by your card issuer or payment provider rather than Derlune™.
02

Paying with PayPal

If PayPal is available as a payment method for your order, selecting it during checkout will direct you to the PayPal payment interface to complete the transaction.

PayPal Account

Customers with an eligible PayPal account may sign in and use an available payment source connected to that account.

Guest Card Checkout

Where PayPal provides guest checkout, customers may be able to complete payment with an eligible debit or credit card without signing in to a PayPal account.

The exact PayPal options available may depend on your location, account status, device, transaction, and PayPal's own eligibility rules.
03

Credit & Debit Card Payments

Eligible credit and debit cards may be accepted through the payment options displayed during checkout.

Because available payment methods can vary by country, device, payment provider, and transaction, customers should refer to the checkout page for the currently supported card options.

  • Enter your billing information carefully and make sure it matches the information held by your card issuer.
  • Payment authorization is subject to approval by your bank, card issuer, or payment provider.
  • An unsuccessful authorization does not necessarily indicate a problem with your Derlune™ account or order.
04

Payment Processing & Card Information

Payment details entered during checkout are handled through the payment services made available on the checkout page.

Derlune™ does not require customers to send complete credit or debit card information to our customer service email. Please never send full card numbers, security codes, or online banking passwords through email or messaging.

For your security, our support team will never ask you to provide your complete card number, CVV/security code, banking password, or other private login credentials by email.
05

Payment Authorization

When an order is submitted, your selected payment provider may perform an authorization check before the transaction can be completed.

If payment is declined, pending, or cannot be authorized, customers may wish to confirm:

  • The billing address and card details were entered correctly.
  • The payment method has sufficient available funds or credit.
  • Online or international purchases are permitted by the issuer.
  • No additional verification is required by the bank or payment provider.

For transaction authorization decisions made by a bank, card issuer, or payment provider, please contact that institution directly for further information.

06

Order & Payment Confirmation

After a successfully submitted order, customers should receive an order confirmation using the contact information provided during checkout.

Please review your order details carefully, including the products purchased, delivery address, and contact information.

If you believe you were charged but did not receive an order confirmation, contact us at service@derlune.com and provide the email address used during checkout together with any available order or transaction reference.
07

Billing Questions & Payment Assistance

If you have a question about a Derlune™ order, payment status, duplicate-looking transaction, checkout issue, or billing information, contact our customer service team before sharing sensitive financial data.

Please provide your order number when available and briefly describe the issue so that our team can identify the relevant purchase more efficiently.
