Shopify's shipping options are limited. Where possible I've tried to make the shipping costs as accurate as possible. But it's an automated process, and not a very clever one at that. So for orders with multiple pieces, it may be prudent to contact me before you purchase to see if I can offer a better shipping price than Shopify calculates. I can always provide a discount code to more accurately reflect shipping costs.
I am a one man shop. While I will do my best to deliver your goods in a timely manner, I have other priorities as well. These duties include but are not limited to being a father, husband, full-time IT professional, knight of The Society for Creative Anachronism, and occasional monarch. This means sometimes I may need a little time to complete your order. If I think that time might be unreasonable, I'll contact you, and we can come to an agreement.
I live in Canada, and I ship via Canada Post. That means when you order from the U.S., you order will be delivered via USPS. There may be duty or other fees beyond my control if purchasing my products from the U.S. My prices are low to reflect that.
