How are shipping costs calculated?

Currently, every product is assigned a flat rate to ship it anywhere in Canada or the contiguous US. So other than possible border duties, it is the same cost to ship anywhere in this range. The cost assigned to each item is decided when listed, and is based around size, weight and how fragile the product is. For example some large or odd shaped items may need custom crates made. All items will be packaged carefully in order to ensure that they arrive to you in proper condition. The cart total shipping is the sum of the individual shipping cost of each product, and HST if applicable
