On the right side of most main pages you can select to add items to your cart in Canadian (CAD) dollars, and also have the option to select CAD dollars on your checkout page. You can then pay by PayPal in CAD dollars, saving on exchange – more $$ for yarn eh!!
The option for paying in Canadian funds is only available to Canadians. All other countries are paid in US funds.
If you have any questions you can email Marsha.
