I have one simple item for $1.50. When I add 2 to the cart I get this subtotal:
    
        
            | Sub Total : | 
              | 
            $3.00 | 
        
        
            | Shipping Fee : | 
              | 
            TBD | 
        
        
            | Handling Charge : | 
              | 
            $0.00 | 
        
        
            | Total (incl. VAT) : | 
              | 
            $3.00 | 
        
        
            |   | 
        
        
            | VAT included (13%) : | 
              | 
            $0.35 | 
        
    
 
It should be 0.39.
 
In Ontario and British Columbia, a new HST (Harmonized Sales Tax) takes effect on July 1, 2010. While we don't need this today, there are less than 53 days to test and implement it. I intend to dig into this deeper but you may find new customers if HST works out the box before July 1st.
