Freight, Free Shipping Thresholds, and Landed Cost on Peptide Kits
2026-04-02 · 5 min read
Per-vial price is not landed cost. Freight and discount tier both move the number.
The formula
Landed cost per vial equals (kit price after discount × kits + freight) divided by total vials. Freight drops out above $2,500.
Where the threshold lands
On mid-priced SKUs the five-kit tier usually clears $2,500, which stacks a 12% discount with free freight.
Consolidate orders
Two small orders in the same week cost more in freight and discount than one combined order at the next tier.
Ordering, minimums, and pricing
Every SKU is priced per vial and sold in sealed ten-vial kits with a one-kit minimum. Volume tiers: 1 kit at list, 2 kits at 5% off, 3 kits at 7% off, 5 kits at 12% off, and 10 kits at 20% off. Domestic orders received by 2PM PT dispatch the same business day, and freight is free above $2,500.
All compounds are sold as chemical reagents for laboratory research use only — not for human or veterinary use.
