Provident Metals To Canada?

Here's what they state on their website;

"International Shipping - We are currently shipping to Canada, but these orders cannot be placed online.
All Canadian customers must call during our regular business hours to place their orders.
Acceptable payment methods are limited to wire transfers, bank drafts, cashiers checks, and money orders for international orders"

There should be no issue with customs if you're buying .999 gold or silver bullion/numis.
Provident should properly describe and declare content. Make sure of that when you talk to them over the phone.
