Not all US banks immediately show debit card transactions. I used to bank at one where the transaction doesn't show up until they try to clear it

And you NEVER see the charges run as credit card until they pay them so it could be days before you even see a hint of the charge.

Care to guess why I changed banks?

You should tell that to my Dell Inspiron 1521 that all Dell laptops have Intel chips. It would laugh at you since it has an AMD Turion64 x2 in it.
