PAYMENT POLICY

Prime Scientific currently accepts the following payment methods: Zelle, Venmo.

These are manually verified transfers. After you place an order we show you the payment details and a QR code. Send the exact order total, include only your order number in the memo or note, and upload a screenshot of your confirmation. Orders are released for fulfillment after our team verifies the payment, typically within a few business hours.

Available payment methods can change. The methods offered at checkout at the time you place your order are the methods we accept for that order.

All prices are listed and charged in United States Dollars (USD). We do not currently support other currencies. Your bank or payment provider may apply its own conversion or transfer fees, which are not set by us and are not refundable by us.

Payment is due in full at the time the order is placed. We do not offer installment plans, net terms, or invoicing.

An order remains in an awaiting-payment state until we verify your transfer. Awaiting-payment orders do not reserve inventory indefinitely and may be cancelled if payment is not received.

The total shown at checkout includes the item subtotal, any applicable payment-method discount, shipping, and any optional coverage you selected. The amount you send must match that total exactly so we can match it to your order.

Sales tax is applied where required by law, based on the shipping destination. Any tax due is shown in the order total at checkout before you pay. Orders shipped to jurisdictions where we have no collection obligation are not charged sales tax; you remain responsible for any use tax your own jurisdiction imposes.

If the amount received does not match the order total, we will contact you at the email address on the order before shipping. Underpayments must be completed before fulfillment. Overpayments and duplicate payments are refunded to the originating account.

If we cannot verify a payment or cannot match it to an order, the order will not ship and we will attempt to reach you using the contact details on the order.

If you believe a charge is incorrect, contact us first. Most issues are resolved faster directly than through a dispute, and we will work with you in good faith.

Filing a dispute or reversal on an order that has already been delivered, without contacting us first, may result in the order being referred for collection and the account being restricted from placing future orders.

We retain order records, payment confirmations, research-use attestations, and delivery tracking, and we will provide these to the payment provider when responding to a dispute.

Refunds are governed by our Returns Policy. Approved refunds are issued to the original payment method or the originating account, and can take several business days to appear depending on your provider.

All products are supplied as laboratory reference materials for in-vitro research use only. Not for human consumption. Not for veterinary use. Placing an order requires confirming that you are 21 or older and that the materials are for laboratory research only. We may decline or cancel any order that does not meet these conditions, and any payment for a declined order is returned in full.

Questions about billing or a specific payment can be sent to info@primescientificlab.com. Include your order number so we can look it up.
