> While the service is being promoted as ‘interest-free’, some were quick to point out that all transactions are subject to a “$4 flat fee”.
$4 in fees on $1000 over 6 weeks is an effective APR of around 4% - pretty good. $4 in fees on $35 over 6 weeks is an outrageous APR of around 123%. I'm guessing Zip is hoping most people are closer to the latter than the former. I wonder what kind of cut Microsoft is getting.
