I've been looking at the Fido website, I'm wondering how they make money out of this. It looks attractive to customers but I worked it out on a $5,000 purchase for 12 months, worked out to be roughly $5,130 in total payments. Wondering where they make money out of that. Perhaps there's a payment from retailers somewhere? Anyone know something about this?

Thanks in advance.
