cop115 said:Just for reference the application of the seller paying the additional sales tax must be a Canadian thing... so I can't really relate as in the US our sellers do indeed just take off 15% and then apply sales tax. Just FYI
The seller doesn't pay the additional sales tax -- there is no additional sales tax. Tax is applied to the actual sale price, not to the original price before discounts. The price is discounted from $100 to $85, so I only have to pay 15% of $85 = $12.75 tax.
If you have to pay tax on the undiscounted price where you live... well, that sucks.
