I think a 28% APR is way high and their tiered financing strikes me as complicated. Do they clearly describe the tiers and payments required to stay in compliance and avoid that hefty interest rate? I bet they don't, that certainly isn't the case with other Synchrony cards.
So then why bother opening a credit card?
Plus, if you're traveling, you really don't want to put hotels or rental cars on a debit card - they put a huge hold on your balance.
Isn't any hold equally large on a credit card? I've never noticed any differences in the size of holds between credit and debit (Finnish VISA cards).
So you don’t want to give someone access to your bank account unless you absolutely have to, since they can “authorize” or “hold” funds in your account which can cause other expenses to not get paid.
Somewhat related, I'm guessing from this that card usage limits are not common in US? Here almost(?) all debit/credit cards have daily limits that you can change via web/app/call, so there can be no arbitrarily sized holds.
1. Cashback. You can expect a minimum of 2% with relatively easy to get cards.
2. Consumer protection. A bunch of this has been extended to debit cards, but it's more of a courtesy from Visa et al rather than a legal obligation. In short, you are legally protected from being made to pay debts that you do not rightfully owe. Anything you pay for with a credit card is incurring a debt rather than giving someone money. This is important because if the merchant uses fraud or misrepresentation and is not willing to fix things, you can assert your legal protection against the invalid debt through a charge-back. If you use cash, your legal recourse is suing them, which at the minimum will cost you a full day in small claims court.
3. Credit card float - buy now, pay a month from now. This isn't as big of a deal as the cash back, since you should have cash at least a month in advance, but at least it gets you the interest payments. The real benefit is that you can largely eliminate non-planned transactions from hitting your bank account balance, which gives you certainty of avoiding overdraft fees. If your everyday spend is on credit, you can look up last month's credit card statement balances and known fixed expenses (like rent) and verify that your bank account will remain positive through the end of the month.
4. Better fraud-handling flow. Your bank has 10 days to refund or give provisional credit for debit fraud. So it means you can be out thousands of dollars for over a week while they investigate. Credit card fraud has a much better flow - the issuer cancels your card and mails you a new one, and never collects any money from you.
2) Benefits - purchase protection, extended warranty, return protection, travel insurance, rental car insurance, free checked bag, etc.
3) Earn cash/miles on purchases.
4) Ease-of-use, I don't have to go to the ATM and take out cash. Sure, I can use a debit card, but that's giving someone access to my checking account, with a credit card I'm playing with someone else's money, I don't have to worry about my mortgage bouncing if there's unauthorized charges, for example.
5) Sometimes required when renting a car.
And various other benefits such as airline and hotel status.
I don’t see a reason to turn down free money.
