I purchase my 100% cotton Warm & White by the roll from Joannes.com. I don't know if they ship to Canada or if they have pay pal, but it might be worth a look. They usually have 40% off sales and sometimes 'internet' specials, where you can get an extra 15% OFF. This week batting is 40% off AND internet special of 15% off so a queen roll is only 190.00 USD. That's a great price.
Good Luck!
