Is it better to sell in Canadian $$$s because of the US - Canadian exchange rates? I always sell in US dollar's because eBay say it's best, but I find I am losing money left right and centre with the current exchange rates -- I lose when the shipping costs are changed into Canadian $$$s when I print out the shipping labels -- I lose again when I transfer money to my Canadian bank -- Would it be better for me to sell in Canadian $$$s ?
