APO Addresses

Your order may be delivered by either the United States Postal Service (USPS) or by a US courier. Depending on your area, most orders will be delivered by USPS so the parcel will be received with your regular mail. If you are not home when the delivery is made, a notice card should be left by the postal service to advise on how and where your delivery can be collected.

Larger orders will be delivered by courier who will attempt to deliver the goods three times or leave with a neighbor. They will also leave a notice card after each delivery attempt to advise you what you can do to arrange receipt of the goods. A signature is required for larger deliveries but not for the smaller USPS deliveries.

Canada Shipping and Handling Costs

It usually takes about 1 business day for us to process your order. As soon as we’ve verified all of your information your order will be shipped via USPS International First.

Arrival time is usually 6-8 days. Remote locations in Canada usually require an additional 1-3 business days for delivery. As custom clearance times may vary, some orders may take up to a total of 20 business days for delivery.

All orders are charged in U.S dollars. Conversion rates will vary depending upon your bank and credit card company. Please contact our bank with questions regarding conversions and fees.
