Lucy Smith became interested in enrolling as a member in Trident Ltd's online discount service for goods and services in exchange for a monthly membership fee. She decided to join up and linked to the enrollment page. The message on the enrollment page promised "up to" $20 off on select purchases including "10% to 40% savings at over 10 000 Participating Restaurants." The form required Lucy to enter her city of birth, credit card number, and contact information, as well as to create a password. Text on the enrollment page also stated that by entering one's "City of Birth" and password and clicking the "YES" button, the purchaser acknowledges that he or she agrees to Trident's "Terms & Conditions." Lucy filled in the form completely and then clicked on the "YES" button. Within a few minutes, Lucy received an email from Trident outlining additional terms and conditions of her agreement with Trident, including a provision which prohibited Lucy from joining any class actions against Trident. Is Lucy bound by this new clause? When was her contract with Trident Ltd complete?
