Any of the card validation services can do a "Pre-Authorization"
transaction, which in effect validates that money is available, and puts a
"hold" on it. Then, you just pass billing the CC number, exp date, and
authorization number, and they do a "Force" transaction, completing the
sale. This is done all the time by companies who don't ship product
immediately... legally, you're not supposed to finalize the transaction
until you ship. I think it was Buy.com that got into a big stink on this
issue last year.
