Credit cards are a widely accepted form of payment, especially when compared to writing checks. Plus, credit cards are usually safer than carrying cash or checks.
If you do not agree with a merchant over an item purchased with your card, you may have the right to withhold payment depending on the circumstances. Buying expensive items with a credit card may provide you with more protection if the item breaks, does not work as advertised, or fails to meet your expectations.
Many cards have grace periods that last as long as 25 days. Essentially, you are given an interest-free loan for a month before you have to pay off your charges. Of course, this strategy is only successful if you pay your balance in full each month.
Credit cards are an extremely valuable source during emergencies that require significant amounts of cash quickly.
You are able to track your personal expenses with your credit card statement. Purchases can be identified by category so you will know where charges were made and when.
