Although most of our products can be shipped normally....
Canada Post considers this product to be over sized.
( more than 20mm thick )
Meaning that it cannot be shipped as regular or oversized letter mail.
It must be shipped as a PARCEL, so they charge more.
Sorry these are Canada Post rules, not ours.
Shipping companies in Canada use the same kind of format.
They charge more based on the dimensions first and then on weight.
What this means is that even a spool of thread...
although it is light as a feather,
still gets charged more to ship it because it is more than 20mm thick.
The flipside of this is, that if you order that spool of thread, the shipping should only be charged once.
So ONE spool of thread will ship for the same price as 23 spools of thread.
And you should be able to get a few more things in there as well, and only pay the one shipping charge.
The system automatically applies this shipping rate to your order.
So if you are local, you may want to choose to pick it up
instead of paying the shipping.
When you get the cart portion of the order...
Just click on the shipping option and chose to pick it up.
