How it works
- Every dollar counts, forever. Tiers are based on your lifetime product spend — not a month, not a year. Sign in to your account to see your exact progress to the next tier.
- Discounts stack. Your tier percentage applies to the already-discounted sale price at checkout, automatically — no code needed. A maximum total discount applies, and a few select items may be excluded from member pricing (they’ll say so in your cart).
- Tier upgrades apply to your next order once the order that crossed the threshold is paid.
- Shipping perks are for US orders. Free standard shipping is unconditional from Researcher up, free 2-day from Apex, and Ascendant ships overnight free on orders of $500 or more (merchandise total, after discounts).
- Spend totals are net of refunds. Sigma Compounds may adjust or end the program with notice; earned tiers are honored while it runs.
