Make a deposit on Saturday and it will not post until Tuesday.
I made a $500.00 deposit on Saturday with a check drawn on the same bank as I use and I received bounced check fees on a check that I wrote today that was deposited today.
They honored the check on Saturday, even gave me cash back on Saturday, but they won't credit my account for three days. There is no justification for that policy except to collect bounced check fees. They knew the check was good or they would not have honored it and given me 1/4 of the cash on Saturday. It's a policy of theft.
