MOST OF THE TIME, if you ship by USPS (not to be confused with UPS), all you need to pay is shipping cost, handling fees ($5), and taxes (GST + PST).Shipping, GST and PST is a given, whether you buy in Canada or from Wayne. Taxes are less if you buy from Wayne because his cost is less. Difference in shipping depends on which part of Canada you're in.
For me, living in Toronto, it's still cheaper for me to buy from Wayne than from Q-Components in Waterloo when I look at total cost. However, it does take longer for delivery.
