Before people suggest bitcoin--and I love bitcoin--it probably wouldn't solve this guy's fraud problem. Yes, it would stop the fraud, but there are simply too few people willing to pay in bitcoin.
I think Facebook or Twitter logins would go s long way to solving credit card issues. A credit card purchase backed by a 10+ friend FB account is unlikely to be a scammer. Legit Facebook accounts probably sell for more than the cc being tested.

I think there are bitcoin escrow payment systems.
The Bitcoin protocol supports multisig transactions. You can use it to implement escrow by including a third party public key and require 2 of 3 parties to sign the transaction.
And then you still have a question of whether the parties agree to a mutually trusted escrow service to actually administer the signoff. I imagine that credit cards are somewhat partnered closer to the customer/card holder, but with bitcoin escrow it could be either the vendor or the customer?
Not meaning to criticise here, just a walking through unfamiliar territory.
Edit: Partially answered my own question (example 2 at link [1])
I think someone else mentioned this in another post about this. Thought it was a great idea so I'll repeat it here: To prevent fraudsters from using you to authenticate their stolen credit cards, set it up so that every purchase automatically redirects to a 'order successful' page. After seeing that a few their credit card numbers all seem to work on your site, the fraudster will realize they can't use your site to t…
Since the candy can't be dispatched instantly anyway, you could arrange it to not affect delivery times.
Though of course, delayed confirmation would also put off genuine customers. So you could faux-confirm it instantly, and follow-up later if there's a problem. i.e. same as parent, but fully automated.

There are several stages of CC validation. EX: http://www.experian.com/decision-analytics/credit-card-verif... M = Full match P = Partial match C = Match, but account is closed L = Match, but card is lost or stolen E = Invalid card number X = No record or security alert N = No match IMO, you can display an error page for some types of issues without helping scammers. However, for physical goods it's a good idea to wa…
I wonder if the techniques for promoting adoption can be used in reverse, to deter adoption?
While keeping it familiar and convenient so as not to deter customers.

Best reply, but... How often is a typo made (1:1000?), how much time for support staff is needed and how many lost orders due to a ~24 hour delay in some orders being placed. Also, easy to flood the system with bad orders that need to be manually sorted, like a fake order DDoS.
If a typo is made 1:1000 times Candy Japan would have had.. 2? At this small scale it's probably worth it - the loss of a customer isn't as big a problem as loss of physical goods.

Thanks, next year I want to get back and try to fix the situation. I fell back to PayPal only and have been losing customers since.
I'm not sure how strict you should go, we have gone to the absolute maximum - and have to deal with customer service issues / abandoned checkouts daily. But even requiring the ZIP code to be correct made a big difference. We're also using shopify which has helped quite a bit with their built in fraud analysis (Not 100% but I think it's either signifyd or kount providing the data). Alternatively, you could use Paypal…
