My kids think I'm cheap because I watch for coupons and make sure I get the most for my money. I was raised very poor and that sticks with you all of your life, it's something that one can't shake. I've used that involuntarily at times to acquire a significant savings acocunt that they are not aware of...otherwise, they might want a loan. And that is another way to save money, don't tell your kids how much you have in the bank.
Or your husband.
