when logging into my authorize.net account, i noticed that they now have 1st American Card Services logo on the account manager
I dont know if theyre owned by the same people, or simply a preferred authorizenet reseller, but if youre looking for authorize.net merchant account, might check them out http://www.1stamericancardservice.com
Their Internet Merchant rates posted on site are:
Fixed Discount Rate 2.32%
Transaction Fee 25¢
Monthly Statement Fee $9.00
Monthly Minimum Fee* $20.00
which, they dont mention it, but you would also have an authorize.net gateway fee on top of that.
