Did you check to see if you can get help paying:
/www.altsampling.com/9068051_canasa/CanasaRegistration.aspx?param=YI ordered from Canada when it was too expensive for me but I can see in your case of meeting the deductible, ordering from Canada would just cause you to pay out and never hit the deductible. I think I pay $40 for canasa with my insurance and copay assist.
