You can't buy guns online as such, in the usual case of out of state customers they've got to be shipped to a Federal Firearms Licensee (FFL) in their state who then does the normal retail song and dance including a NICS background check. But of course the big money part of the transaction will be done before that, and almost certainly as a credit card transaction, as was the case for my last gun purchase (see e.g. http://www.gunbroker.com/ http://www.gunbroker.com/ where I half-bought that one, and how many firms on it offer payment by credit card (the flip side of course is that if you're an individual selling a gun, or a bare receiver as I did once, you of course are going to have to go the cashier's check/money order/personal check route (no PayPal, of course))). And I've never heard that firearms and their accessories including ammo being a fraction of financially risky like porn, e.g. no one dancing to the tune Operation Choke Point cites that sort of risk, vs. it being a purely political decision. Plus it's just plain more serious of an industry, e.g. no one needed a Federal background check to buy porn (!). And there are many merchant banks that have affirmatively decided to provide credit card processing services to such companies at normal rates, for references to one offered in part as a enticement to join, see http://nssf.org/didyouknow/?iurl=payment-provider-offers-services-to-nssf-members http://nssf.org/didyouknow/?iurl=payment-provider-offers-ser... from the nation's gun industry association (the NRA is the gun owner's one).
