I love the options for DDP which helps our Canadian customers,
Unfortunately, the most economical way to ship our product is USPS First-Class Package International which does not have an option to DDP
From ShipStation's DDP article:
"USPS (limited to First-Class Mail International, Priority Mail International, and Priority Mail Express International from the US to Canada only for shipments under 4 lbs)."P
Please add this option especially for since Amazon requeires sellers to cover dutites and taxes.
