Haha. I use my check card but I always push the credit button because its much safer. I only write checks when I pay bills and I almost never have cash.
For some reason if I am carrying cash and my debit card, I will use the debit card. It appears in my own little justification that I am not really giving away my cash. But for some reason, I hold cash more valuable than credit or debit.
I used to charge everything to my debit card....This one time I forgot to deposit my paychecks so I had to pay about $350 in overdraft charges...I still charge but now I make sure its to my credit card and not the debit....
I definately feel like less of an idiot, now that I know other people have done the same thing....Wish the card wud jus stop workin after u ran out of money instead of chargin u like a million dollars per transaction....
