Shipping

Canadian orders

For orders that are $399 and below (after discounts, not including shipping fees), we are now including all Duties and taxes with shipments.
For orders over $399, we can not cover these costs, sorry!

UK & Northern Ireland Customers:

Our prices include applicable duties, local taxes, brokerage fees, and VAT. Your package will be delivered directly to your door.

🚨 International customers

Unfortunately, our prices don’t include local taxes, duties, brokerage fees, and VATs, all the stuff you may be charged to receive your shipment at home. Make sure you consider all fees, because once your order arrives you’ll be required to pay all additional charges — and we won’t be able to refund you if you change your mind!

Can’t find your country?

We offer $28 shipping on all orders to countries not listed above.
