Shipping Policy

Last updated: October 28, 2026

Where we ship

From this site we ship to all 50 US states and Washington, D.C. We currently don't ship to P.O. boxes, APO/FPO addresses or US territories.

Cost

Standard tracked shipping is free on every US order. Prices shown at checkout include any import duties, so you won't pay anything extra at delivery.

Processing and delivery times

• Processing: 1–2 business days (Monday to Friday, excluding US holidays).
• Delivery: usually 7–12 business days after your order ships. Some products ship from our international fulfillment partners, so delivery can take a bit longer during peak seasons.
• If you order several products, they may arrive in separate packages.

Delivery dates shown on product pages are estimates, not guarantees.

Tracking

You'll receive an email with your tracking number as soon as your order ships. If you can't find it, check your spam folder or email us.

Address issues

Please double-check your shipping address at checkout. If you notice a mistake, email us right away and we'll update it before your order ships.
