There is no other fee. (NOCA = No Other Fees Apply). There is a minimum transaction size, currently at $2.00 i.e. Noca will not accept transactions less than $2.00

It was indeed too good to be true. I think you guys should mention that on the site.

It's not really fair to compare yourself to Amazon's micro transaction fees but not actually accept micro-payments.

Bummer. 99% of our transactions are $1, and so far PayPal is the only merchant that supports this.
