Most common reason is your charge company (their information is printed on back of your credit card) blocks your order to prevent and protect you from international credit card fraud.
Please contact your charge company and inform them that you are going to make an international online purchase from Canada, and a charge from Biosense Pharmacy will be coming. This is Visa & Master Card’s new policy for out of country purchases. If you do not phone prior to our billing, your order could be delayed.
If you still having a problem ordering, please email: order@biosensepharmacy.com with an email title “International order”. Please email us your full name and inform us the details of error you are experiencing.
