They don't disclose during the purchase process that the authorize.net is only SIM which is a discontinued process by authorize.net. It's insecure, requires the customer to leave your site, and looks like crap. They really need to tell people this. It's other places in the site, but when you are purchasing it it does not tell you. Not only that, the other features have a lot of bugs. It does not work well. I've gone back to wp-ecommerce.
