Large purchases. Debit cards are designed for everyday purchases, not big-ticket items. If you use your debit card to buy a car or a TV, you could overdraw your account and be charged overdraft fees.
Online purchases from unfamiliar merchants. When you shop online, make sure the merchant is reputable and secure.
Recurring payments. Recurring payments, such as gym memberships or streaming services, can be easy to forget about. If you don't cancel them properly, you could end up overpaying.
Gift cards. Some gift cards can only be used at certain stores or online retailers. If you lose or damage the gift card, you could lose your money.
Charitable donations. When you donate to charity, it's best to use a credit card instead of a debit card. That way, if your card is compromised, you won't lose any of your own money.
International travel. Debit cards can be expensive to use for international transactions. There are often high fees for foreign currency exchange and ATM withdrawals.
Cash advances. Cash advances are a type of loan that you take out against your debit card balance. They typically have high interest rates and fees, so it's best to avoid them.
Paying bills. You can usually pay your bills online or over the phone without using your debit card. This will help you avoid overdraft fees and keep your account balance more secure.
