All items are shipped via Canada Post and are shipped prepaid. All orders are processed and shipped as quickly as possible. Usually orders are shipped within two business days of receipt of payment. Many times orders are shipped the very next business day. However, there are times due to high order volume, when it may take up to 3-4 business days to ship. Regardless of order volume, we guarantee all orders will be shipped from our warehouse no later than 4 business days from the time payment is received.
Regarding carriers, we make no guarantees as to the time a carrier may take once an item is shipped. We are not responsible for any delays due to a carrier's lack of performance. A special note during the holidays, the period from Thanksgiving to Christmas is an especially slow time to receive shipment. Please be patient if you are waiting on a parcel during this time. Again, a carrier's lack of performance is out of our control.
Any incorrect addresses will have charges from Canada Post and will be billed to the customer, such as missing apartment numbers, incorrect zip codes, and so forth. These incorrect address mistakes result in your parcel being returned to sender. This fee is billed by Canada Post separately to us, so please be sure to double check your address information before submitting order. In placing your order, verify that your shipping address is complete and correct. Should the address information provided be incorrect, Canada Post will ship the parcel back to the sender and the sender will be billed for this. If you wish to receive your order after this has happened then we will have to charge you for the return shipping fee and the re-shipping fee due to the incorrect address the customer submitted.
