Implement a fraud detection service that blocks suspicious transactions based on where they originate Cheap Cigarettes Online USA, or other factors. If you can't reach the cardholder, don't ship the merchandise. People who use stolen credit cards don't give out their real phone numbers.
Look up the address and phone number of any local orders in the phone book.
Send a reminder letter to people when you ship an item telling them the item has been shipped and when they can expect it to appear on their bill. This type of letter can reduce complaints and chargebacks from people who simply forget what they ordered or from whom.
NOTE: Don't automatically discredit an order that looks suspicious. I once had someone place an order and ask that it be shipped to Mickey Mouse. My order form includes a place for an e-mail address, and the person had included their e-mail address, so I sent them a note to ask about the order. The individual, who had used his real credit card data and real address for shipping had used the name Mickey Mouse, because he was afraid to use his real name on the Internet.
