.2% premium over interchange sounds fair given the volume that you are doing. If you can grow your volume to about $1mil a month, I would push for around .05% premium. Usually rate shopping with other companies is the best way to get the fees down. Costco used to offer a great rate. Another to check is Litle.
Also, based on your volume the rate here is .09%. [naccadirect.com...]
