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

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

Orders may be subject to transaction authorization, payment verification, identity verification where applicable, and 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 and authorization-hold periods are controlled by the applicable financial institution or payment provider.

Checkout is processed through Shopify together with applicable payment providers using technical and organizational security measures intended to protect transaction information.

Alzervin™ does not store complete credit or debit card numbers on its own store servers. Payment information is handled through Shopify and the applicable payment services involved in processing the transaction.

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

Prices on alzervin.com are displayed in U.S. dollars (USD) unless another currency is clearly shown.

Please review your products, quantities, shipping information, promotional discounts, and final total carefully before completing payment.

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

These charges are determined and collected by the applicable financial institution or payment provider and are not charged or controlled by Alzervin™.

Valid promotional or discount codes 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 expiration dates, product eligibility, minimum-purchase requirements, exclusions, usage limits, availability, or other conditions presented with the applicable offer.

If a payment is declined, please check that your billing details are correct and contact your bank or payment provider if necessary. A pending amount may represent a temporary authorization rather than a completed payment.

If you believe you were charged more than once for the same order, contact us with your order number and the relevant transaction details. For your security, do not send complete card or banking credentials by email.

After an order is successfully submitted, an order confirmation will normally be sent to the email address provided during checkout.

If you do not receive a confirmation email, please check your spam or junk folder and confirm that the email address entered during checkout was correct. You may also contact customer support for assistance.

If you believe a payment was charged incorrectly or you have a question about checkout, please email service@alzervin.com .

Please include your order number where available and a clear description of the issue. For your security, do not include complete credit-card, debit-card, or banking information in your email.
