In the future we would like to give you a way to advertise a variety of specials and discounts for your customers on your personal website.
In the meantime, they will not see specials you offer reflected at checkout. Your customers will see suggested retail, shipping + handling, and sales tax. You can apply any discounts prior to charging their method of payment; however, you may opt to not offer specials through your website to simplify the process for your customers. The choice is yours.
