Final answer:
24/7 website access is a non-monetary incentive that businesses use to motivate customer engagement by offering convenience and flexibility.
Step-by-step explanation:
Access to a website 24 hours a day can be considered a non-monetary incentive. It serves as a motivation for behavior or action without a direct financial reward. Businesses may offer 24/7 access to their websites as a way to encourage customers to shop or engage with their services at any time, which provides convenience and flexibility.
This is similar to the concept of opportunity cost where one might pay someone else to wait in line, consequently freeing themselves to engage in other valuable activities.
