I was wondering what payment module I should use. The way we price products is we set up the shipping depending what the product is. So we may charge $17 for one product and decide to charge $4 shipping to the US and $8 shipping internationally. For another product we may also charge $17 but decide to charge $6 shipping to the US and $10 shipping internationally. What would be the best way to set it up so we can put in the shipping price for each item that we add.
