Agree completely. Also, if you look at the top of the AP fee page it specifically states:
"Amazon Payments offers low, predictable pricing. You only pay when you process payment for a transaction made on your website. No monthly charges, long-term contracts, or hidden fees.

Amazon Payments fees are transaction-based. Your fee is based on a percentage of the transaction amount plus a per-transaction fee. Our standard rate is 2.9% + $0.30 per transaction for transactions of $10 or more. To help lower the cost of accepting payments, we offer discounts for volume, micropayments and processing donations. See below for details on our fees and discounts."

We are not processing payments on OUR own website. We are using the AP website so there should be no charge.
