Here’s what consumers have asked with answers from MyUS staff and previous consumers.
This is how the MyUS service works: You register for a membership with MyUS. We provide you with an address in the US which you will use when placing online orders. The merchants will ship your orders to MyUS and then we will forward the orders to the shipping address of your choice. You would be charged for the membership fees plus the shipping fees of your items.
Our shipping rates for Canada are based on the weight of your package, as well as the courier you choose and even your membership type! You can use our Ship Rate Calculator to estimate shipping costs: http://www.myus.com/en/international-shipping-rates/
