Is there any danger to giving out a check routing number for a purchase? I gave out a routing number and now concerned that it could be used to draw out more then I authorized.

    The routing number identifies the bank and possibly account type, not the customer. That number is public anyway. You mean the account number?

Not really any more dangerous than giving out a physical check with the exact same information printed on it.
You'll notice signs in many stores which tell you in one way or another that if you give them a check they're going to process it electronically - which ends up being the same as if you're just giving them the routing numbers off the check.
