# Oath Research shipping and returns > Oath Research's shipping cutoff, delivery area, and complete return and refund policy — including exactly what qualifies for a refund and what does not. The two promo codes on this site are only useful if you know what happens after checkout, so this page covers Oath Research's actual shipping and return terms in one place, drawn directly from Oath's own published policy. In short: most orders ship on two-day air with a same-day dispatch cutoff, tracking is automatic, and returns are available in specific, clearly defined cases tied to product quality or shipping error rather than a general change-of-mind policy. None of this is exclusive to orders placed with a promo code — it's the same policy for every Oath order, discounted or not. ## Dispatch cutoff and delivery method Orders placed before 12:00 p.m. MST, Monday through Friday, ship the same business day. Orders placed after that cutoff, or over a weekend or federal holiday, ship the next business day instead. Most orders go out on two-day business air, typically via UPS where available, with real-time tracking provided from the moment a shipping label is created — not added on as an afterthought once a package is already in transit. Oath's stated guarantee covers dispatch on that schedule, not a specific arrival date. Once a package leaves Oath's facility, transit time is up to the carrier, and Oath doesn't promise a delivery window it doesn't actually control — a more honest guarantee than a flat "2-day delivery" claim would be. Federal holidays follow the same next-business-day rule as weekends: an order placed on a holiday, or a cutoff that falls on one, pushes dispatch to the following business day rather than the calendar day after. ## Cost and delivery area Orders over $250 ship free; orders under that threshold carry a shipping charge calculated at checkout based on package weight and destination. Oath ships within the United States only — it does not offer international shipping of any kind, so an order placed from outside the US, or shipped to an address outside the US, won't go through regardless of any promo code applied to it. Real-time tracking is provided on every shipment regardless of order size, so the free-shipping threshold affects cost only, not whether a package can be tracked in transit. There's no separate expedited option mentioned in Oath's stated policy beyond the standard two-day air service — the $250 free-shipping threshold determines cost, not speed, since the same two-day dispatch-and-transit target applies to orders above and below it alike. None of these terms shift based on which of the two promo codes is used, or whether one is used at all — shipping cost, delivery area, and tracking are calculated from the order itself, separately from whatever discount was applied at checkout. ## What qualifies for a refund or replacement Oath will refund or replace an order in five specific situations: the product doesn't meet its stated specifications or purity, the shipment arrived damaged in transit (photo evidence required within 48 hours), the wrong item was shipped, tracking shows the order as delivered but it never arrived, or a duplicate order is caught and reported before it ships. There's no restocking fee on an approved return. Oath states a response time of 24 to 48 hours and a refund processing time of five to seven business days once a return is approved. Each of these five categories is a specific, checkable failure — a purity result that doesn't match the certificate, a package that arrives visibly damaged, the wrong product in the box, tracking showing delivery to an address that never received it, or two orders placed and shipped when only one was intended. None of them require guessing at Oath's intent; each has a concrete condition attached to it. ## What doesn't qualify Opened or used product isn't eligible for return — standard for research material rather than a policy gap specific to Oath. The same goes for product that was mis-stored after delivery, an order canceled after it's already shipped, or a straightforward change of mind after an order goes out. Read together with the qualifying list above, the policy is narrow but genuinely enforced: it protects against real failures — wrong purity, damage, non-delivery — without functioning as an open-ended return window. The line Oath draws is consistent with how research material is generally handled industry-wide: once a vial or product has been opened, its condition can no longer be verified by the seller, so the return option closes at that point rather than staying open indefinitely. None of this is unusual for the category, and none of it is a way of avoiding a legitimate claim — the specifications-and-purity guarantee in the previous section is the actual test, and it applies regardless of a promo code, order size, or how the order was placed. ## How to pay Oath accepts Visa, Discover, and American Express, plus direct bank payment, processed through a PCI-DSS compliant payment gateway with end-to-end encryption, per Oath's own stated security practice. Mastercard is not listed among the accepted card types as of this writing, which is worth knowing before filling out an order's worth of shipping and billing details only to find the card declined at the last step. A promo code and a payment method have nothing to do with each other — nothing about using either of the two codes above changes which payment methods Oath accepts, and nothing about a chosen payment method changes whether a code applies. Direct bank payment is listed as a separate option from the three card types, which is worth knowing if a card isn't the preferred method — payment here isn't limited to card types alone. None of the four payment options carries a separate discount of its own; the two promo codes are the only price adjustment in play regardless of which one is used to check out. ## Ready to use a code?
