One last pause before you pay.

When your first order is nearly ready,

When you're ready, head to Oath Research’s homepage. You'll place your order and pay there. For new customers, GRANT gives 20% off the first order. The alternative is GRANT15: 15% off for everyone, repeat orders included, with no minimum. Pick one code to use at checkout.

Look for the saving before the order goes through.

Paste your chosen code into the shop's coupon box and apply it. Then look at the discount and the amount due. If the saving is missing, check that you've copied the whole code and that the offer fits your purchase history. Ask Oath Research for help before paying if it still doesn't apply.

Leave a little time for the shipping details.

• Check your US delivery address. Oath Research ships within the United States only.
• Read the shipping charge at checkout. Free shipping is for US orders over $250. It's unclear whether the shop uses the amount before or after a discount, so check the charge on your order.
• Most orders use 2-day business air, typically UPS where available. Orders placed before noon MST, Monday to Friday, ship the same business day; later orders, weekends and federal holidays ship the next business day. That is a dispatch schedule, so leave room for carrier delays.

Before you finish, reread the description of the research-use-only material. Oath Research offers a refund or replacement if a product doesn't meet its stated specifications or purity; opened or used products can't be returned. If you have a question, the shop publishes +1 480-999-1097 and gives a support response time of 24–48 hours. You can wait for an answer before placing the order.
