Re:Customer information sharing (Score 2, Interesting)

Or he *returned/exchanged* a product purchased on his credit card to the store in the past and they asked him to fill out one of the return forms with name and address. Now BB has tied his address to his credit card, so he's now populated in the database with full name and address.

When he purchased the Blu-ray player, it used his credit card to lookup his record and put the purchase down on his record, even though he didn't supply his personal info at that time.

Then, when it comes time to mail out updates, they just lookup all transcations with the player, pull the purchaser info...bang.
