Been a pretty common occurrence lately has happened several times my card will get charged twice for the same item which then in turn keeps me from that much o my available balance and has put my acct. in the red which then costs $  CROOKS

This is standard operating procedure for banks.  The amount of the charge is held until the actual charge goes through.  It falls off at that time.  No one could see it before online banking, but it has always been this way.  If you look when you pump gas, this is printed on a sticker.

I used to work at a bank so I saw this all the time.  Easiest explanation is that a check can be returned for insufficient funds, but a debit card purchase cannot.  The amount is held and the debits are taken out first and then the checks are paid.
