Earn better account pricing as your research purchasing grows.

How tier status works

• Membership is free; there is no paid membership fee.
• Qualified spend uses completed and processing product purchases from the trailing 12 months.
• Your tier refreshes automatically as qualified orders are completed and older purchases roll outside the 12-month window.
• Sign in before checkout so the current account price can be applied.
• The best eligible discount wins. Membership pricing, coupons, quantity pricing, and promotions do not stack.
• Shipping, taxes, refunds, cancelled orders, test orders, and free gifts do not count toward qualified spend.
