I use checks mainly for paying for bills, guess it's a holdover from when I was a bookkeeper many years ago. Funny I never liked having my checkbook in my purse for fear someone would steal it but have no fear carrying my credit card in my purse.
I always drop any mail that has a check in it at the post office. Years ago a gang of thiefs went through our area breaking into post office boxes in strip malls and on street corners, they accessed our joint account and my personal checking account. Come to think of it the only place I've seen a post office box recently is in front of the post office. May in Jersey
