Ejay's Éclairs is a small, exclusive pastry shop that has recently decided to use its website to deliver catered goods locally on Prince Edward Island. With the hope of cutting down on roaming charges, Ejay has designed an online ordering system that automatically forwards orders to her mobile email device. Worried that some orders may slip between the cracks, Ejay wants to add a provision to the terms of use on her website to exclude liability for any late or undelivered orders, minimizing her exposure to a refund plus a gift certificate. At the same time, Ejay does not want to burden her customers with an online registration process. What legal principles are at play? How should Ejay set up her website to ensure that the terms are effective?
