OK, I'll use my insider information here -

NEVER EVER EVER EVER use a Debit Card if can use a CREDIT CARD. Just make sure you can PAY IT OFF IN FULL


Why?

1. The consumer protection laws for CREDIT are much much stronger than for DEBIT.

2. DEBIT transactions rarely give you miles, points, cashback, whatever.

3. DEBIT cards can put a FREEZE on your BANK ACCOUNT for HUNDREDS AND HUNDREDS OF DOLLARS if you use them in hotels or for rental cars, as they block out your "potential" charged.

Don't use debit cards except as an ATM card.
