Because some books are available to Canada, Canadian IP-address are allowed. So if you have a Canadian IP-address you do not have to use an US VPN, just changing the addresses to an US address is enough (with a Canadian address you will only be allowed to buy the small number of books available to Canada).
As the billing address is not checked, a Canadian credit card will work fine.
