Bank Fees from Federal Regulation D

I spotted something interesting in the monthly newsletter from my credit union that has helped explain a series of pesky transfer fees I incurred several years ago.  It has to do with Federal Regulation D.

Federal Regulation D, as it's name so clearly indicates, is a banking rule.  It limits the number of withdrawals from a savings or money market account to only six per month.  If you regularly transfer funds from your savings to your checking account, you could get charged a fee if you make the transfer more than six times in a month.
