A note before your first purchase.

# The oath new customer discount: choose your invitation.

Cart record: checked 19 October 2026

If the sign-up banner brought you here,

You're right to compare the offers before placing your first order. Oath Research's homepage displayed “NEW ACCOUNTS SAVE 15%” on 19 October 2026. The code GRANT gives new customers 20% off their first order. That's the bigger percentage, and it's a separate offer from the sign-up banner.

## Choose one saving to rely on.

Choose one offer when planning your purchase. Don't count on adding the codes together or combining either code with the banner. Apply your chosen code at checkout and look at the saving shown there. If the amount doesn't make sense, pause and ask Oath Research before paying.

You may also notice that the banner and GRANT15 show the same percentage. They have different terms: GRANT15 gives everyone 15% off, includes repeat orders and has no minimum. The banner is for new accounts. If you've bought before, the repeat-order code is the one to consider.

## Leave time to register and read.

The homepage also said on 19 October 2026 that you'll need an account to browse the product catalog. Once you've registered, take time to read the description and available batch documentation for the research-use-only material you're considering. A larger discount isn't a reason to skip those details.

Before you finish, check your destination, shipping charge and final total. Both codes applied in the logged-out cart record dated 19 October 2026. That tells you what happened in that cart. Please check the saving on your own order before you place it, too.

When you’re ready

You're welcome at this Oath Research deals page, where nothing from either code comes back to us.
