Profit is estimated by what you are charging your customer minus what you are paying Lulu on a per order basis. You should determine the cost of your Lulu Direct product based on what you will have to pay us for production and shipping. This will include printing, the per order fulfillment fee, shipping, and taxes (if applicable).For example (excluding taxes): If you charge your customer $20, including shipping, and it costs us $4.50 to print, $4 to ship, and $1.50 for the fulfillment fee, your estimated profit will be $10.Note: Estimations may vary if you are charging your customer in a currency other than the currency you are paying Lulu in.
