I saw a very interesting 1hour program on TV a while back about credit card scammers, its pretty much standard for these people that have managed to get hold of someones credit card details(there are websites that list them
) to 'test' the card by purchasing something at random, and sending it to some random address with a random name on it(pulled from phone book).
They're not interested at all in the item from the 'test' purchase or even seeing if it gets delivered, they just want to know if the card can be charged to, if it works they then spend up big and ship to an address they can collect from.
In the program, the reporter got a new credit card from a bank, told them what he was doing and they helped him with the investigation. They listed the cards details on one of those sites and sat and watched all the transactions 'live' on the banks computer.
Within seconds the card was being 'tested' by people from all over the world, just little purchases like $20 here $10 there etc, within mins the card was was being used for $1000+ purchases, the reporter then chased up the purchases thru the vendors and got adresses and then posed as a fedex courier making the deliveries to confront the scammers.
There was a woman(who acted as an inbetween, a delivery address) who's house was so full of packages it looked like a warehouse, she had no idea what was in any of them, she got paid when people came to collect.
