Payment: Paypal Invoice will be sent to your email. You'll be able to make a payment with credit card on Palpal even if you don't have Paypal account.
Shipping to CANADA: Sorry to say this but we had very long delay on delivery in Canada these days and it takes even two months occasionally when you suffer from bad luck.
In the case of trouble you have to wait two months(plus a week) before having me issue fully refund. If you are in Canada consider using EMS for shipping method, which is traceable and very fast(3 days or so) but it costs
20USD instead of 6

Let me know if you want to use EMS.
Lead TimeThe converters can be shipped usually in a few working days.
