The payment methods currently available for your Lungpex™ purchase are displayed during checkout. Available options may vary depending on your location, currency, device, order details, and the payment services available when your order is placed.

Please select one of the payment methods shown at checkout and follow the applicable instructions to complete your purchase.

Because available payment options can change over time, the payment methods displayed directly at checkout are the most current options available for your order.

Orders may be subject to transaction authorization, payment verification, identity verification, or fraud-prevention review before an order is accepted or fulfilled.

Your bank, card issuer, or payment provider may request additional verification, decline a transaction, or place a temporary authorization hold on your account.

These decisions, verification procedures, and authorization hold periods are controlled by the applicable financial institution or payment provider rather than Lungpex™.

Checkout on lungpex.com is processed through Shopify together with applicable payment providers using technical and organizational safeguards intended to protect transaction information.

Lungpex™ does not require customers to send complete payment-card or online-banking credentials to our customer-support team by email.

Before payment is submitted, checkout displays the applicable product prices, shipping charges, taxes where applicable, discounts, and the final total for your order.

Please carefully review the Lungpex™ products selected, quantities, shipping details, discounts, and final order total before completing payment.

The currency shown during your shopping and checkout experience should be reviewed before payment is submitted, particularly if you are purchasing from outside the United States.

Your bank, card issuer, or payment provider may separately impose foreign-exchange fees, international transaction fees, currency-conversion charges, or other financial-institution fees.

These charges are determined and collected by the applicable bank, card issuer, or payment provider and are not separately charged or controlled by Lungpex™.

If a valid discount or promotional code is available, it should generally be entered before checkout is completed. Please confirm that the applicable discount appears in your order total before submitting payment.

Promotions may be subject to product eligibility, expiration dates, minimum purchase requirements, exclusions, availability, usage limits, or other terms presented with the applicable offer.

Certain offers may apply only to selected Lungpex™ products, collections, or seasonal promotions.

If your payment is declined, first review your billing information and payment details. You may also need to contact your bank, card issuer, or payment provider for additional information.

A pending amount on your account may represent a temporary authorization rather than a completed transaction. Authorization-release timing is generally determined by the applicable financial institution.

If you believe you were charged more than once for the same Lungpex™ order, please contact customer support with your order number and a description of the transaction issue. Do not send complete card or banking credentials by email.

After an order has been successfully submitted, order confirmation information is normally sent to the email address provided during checkout.

If you do not see an order confirmation, please check your spam or junk folder and confirm that the email address entered during checkout was correct.

If you still need assistance, contact our customer-support team and include the name and email address used when placing your order.

If you believe a payment was charged incorrectly, see an unexpected transaction status, or have another question about checkout, please email service@lungpex.com .

Please include your order number where available, together with a clear description of the issue.

For your security, please do not include complete credit card numbers, card security codes, online banking passwords, or complete banking information in your email.
