Shipping is shown as a separate line at checkout before you pay. Any applicable state sales tax is calculated and displayed at checkout.

How long it takes
  • Processing: orders placed before 12:00 ET on a business day are usually dispatched the same or next business day. Orders placed at weekends or on US public holidays are dispatched on the next business day.

  • Transit: Standard Ground, typically 2–7 business days depending on distance from New Jersey. Alaska, Hawaii and US territories take longer.

  • Total: most customers receive their order within 3–8 business days of ordering.

These are estimates, not guarantees. Carrier delays, weather and peak periods can extend them.

Tracking

You will receive a dispatch email with a tracking number as soon as your parcel leaves the warehouse. Tracking can take up to 24 hours to show movement.

Subscription deliveries

Subscription orders are created and dispatched automatically on each renewal date. Update your delivery address in the subscription portal at least 3 days before your renewal date — once an order has been dispatched we cannot redirect it.

Address accuracy

Please check your delivery address carefully. We are not able to refund orders lost because of an incorrect or incomplete address supplied at checkout, though we will always try to help recover the parcel.

Undeliverable and returned parcels

If a parcel is returned to us as undeliverable, we will contact you. We can reship it once you have paid a new shipping charge, or refund the product price less the original shipping cost.
