Zelda is selling her tennis racket on a popular website for selling used goods to help with expenses when she goes to university.
The website where Zelda is selling her tennis racket provides a secure electronic payment system to transfer money from buyers to sellers.
Recently, Zelda had the following exchange with an interested buyer through the website’s messaging system
NinaB2: Hi! Your tennis racket looks really nice, it’s a great model.
Ze1dA: Thanks :) Are you interested in buying it?
NinaB2: Your racket is worth more than 150 zeds. If you give me your bank account details, I can make a bank transfer directly for 200 zeds and you can send me the tennis racket. What do you think?
Ze1dA: Thank you for the offer, but I’d prefer to use the website’s payment system.
