加拿大采购需求：门到门配送、海运、空运、铁路运输、海运门到门、国际空运

I'm looking to purchase a sofa from China and would appreciate it if you could provide me with an estimate of the total cost, including shipping from Foshan to my location in Canada (H7C2N1). It would be great to understand the pricing structure, including any potential bulk discounts or additional fees I should consider. Additionally, I'm interested in learning about the entire purchasing process, from selecting the product to final delivery. Specifically, I'd like to know about payment terms, estimated delivery times, and any other logistics involved in importing furniture from China. Your insights will help me make an informed decision. Thanks!
