Qelvazio™ uses online payment only. Major U.S. credit and debit cards (including Visa, Mastercard, American Express and Discover), PayPal, and eligible accelerated checkouts such as Apple Pay, Google Pay and Shop Pay may be used when enabled and shown at checkout. Availability varies with the buyer, device, location and payment provider. Cash on delivery (COD) is not offered.

Qelvazio™ does not collect cash payments on delivery. Please complete the available online checkout payment flow to place your order.

Payment providers may pre-authorize or verify a transaction, require additional authentication, or decline a payment under their security and risk procedures.

If a payment fails or requires verification, follow the instructions provided by the checkout payment service.

Enter payment details only through the store’s normal checkout and the designated secure payment provider. Never disclose one-time passwords, PINs or card security codes to a customer-support representative.

Qelvazio™ support staff should not request complete payment-card credentials via email, social media or phone.

All product prices are presented in the checkout currency. For eligible U.S. orders, Standard Shipping costs $2.99 USD and Express Shipping costs $5.99 USD. Any applicable taxes, discounts and the final payable amount appear before you confirm payment.

Review your items, quantity, delivery address and selected service before authorizing payment. Bank or payment-provider conversion fees may apply independently.

Your bank or payment provider may apply international transaction fees, currency-conversion charges or temporary authorizations. Please contact that institution for details about fees outside the store’s control.

Promotional offers apply only when the relevant conditions are met and the discount is accepted by checkout. Campaigns can have eligibility conditions, exclusions or expiry dates.

If a payment is declined, verify the payment details and any additional provider instructions before trying again.

If you believe a charge was duplicated or made without authorization, contact customer support with non-sensitive transaction information and consult your bank or payment provider as appropriate.

Requests for eligible returns or exchanges can be initiated within 30 days of delivery, in line with our Return & Refund Policy. If a refund is approved or required by law, it will normally be returned to the original payment method where supported. Posting time depends on the payment processor, card issuer or bank.

Retain your order number and receipt. If your account shows a charge but no order confirmation, please contact us so we can review the transaction.
