I have an ecommerce store that does quite well and I have been using paypal with 1shoppingcart for a while now. I notice that several times a week people dont finish payment because they think they need a pay pal account in order to pay, so I switched to authorize.net. Since doing so my sales actually seem to be down, not to mention that its one hell of a confusing system.
It could be a coincidence but I was wondering if anyone else has had weird results after switching to authorize.net. I'm almost tempted to switch back.
