What are the reasons to get more than one credit card?
I keep one card just for monthly bills (power company,car loan, etc.).  This one is unlikely to get hacked so I won't have to go change the credit card information on my monthly bills.  I pay the credit card from my bank account.  I just don't want a lot of businesses with direct access to my bank account.
