Credit cards are a great tool and I always recommend people get one and use it responsibly.
With a credit card you have a massive increase in consumer protection - if you pay for something and a dispute arises, the credit card company is your friend. Not often a billion dollar multinational will side with you.
I advised my girlfriend the same - within a week of getting it she used it to buy a large pet cage. The seller never sent the goods, and didn't answer the phone or respond to emails. She contacted the credit card company, who then issued a chargeback against the seller and she got her money back.
You could never do that with a debit card - instead, you'd have to mess about with Trading Standards and have the hassles of taking out legal action yourself if required.
Hassle saved by having a credit card - but as with all tools, use it responsibly.
I pay mine off in full at the end of every month, as it should be.
