As you've probably heard by now, BofA is responding to the new caps on debit card transaction fees by charging its customers
$5 a month to use them.
I don't expect I'll leave BofA over it, but I have absolutely no problem with cutting up my debit card. I only use the thing at ATM's and at the start of the month when my credit card bill is due. I've already got an ATM card for the former, and I'm careful enough to pay the latter immediately if I end up using it around the due date.
Funny thing is, if they'd made it fifty cents a month nobody would have balked and it would have still made them hundreds of millions of dollars. And yes, I realize 90% of their customers would have to leave for them to make as little money on $5 a month as they would for a tenth of that amount, but not all costs come in direct monetary form. The big banks already have a not-so-favorable public image, and a fresh thumb-in-the-eye to customers isn't what you would call mitigation.
