We use UPS in the USA and either UPS, Purolator, Canpar or Canada Post within Canada. Orders may take 1-2 business days to process. A tracking number will be provided by email. US Customers are c harged 5.5% for duties (it appears as "Federal Tax" in your checkout ) on all items, but you are not charged either US or Canadian tax, since neither are legally applicable . In other words, we charge 5.5% duty to all US orders, we pre-pay the duties to US customs (so you don't have to deal with them ), and you don't pay a cent of tax. Not a bad deal, especially considering the strength of the US dollar!
