I recently sent an international postal money order to Canada to purchase a product. How long a time should I wait without receiving the product before I get a refund for the money order ?

Have you contacted the company or whoever you are purchasing the product from? Or is there anyway of tracking your purchase? I would say it depends on when the item was expected. Like say it was expected to arrive in 4 to 6 weeks and it'd only been 5, I'd say wait. But if you were expecting the product to come by a certain time and it hadn't and the company wasn't doing anything to resolve the problem, that's when I'd be asking for a refund.
