Credit cards and their benefits

The idea of a credit card is great... Just spend money! Ayyy! But there are serious advantages to them...

Credit cards may sound unlikely for a young apprentice to consider but could it be a way of saving money and being rewarded while spending? Credit cards effectively let you buy things, but you pay for it at the end of month- like a short-term loan. Throughout the time that you use your card you will gain a credit score, be protected on purchases and (depending on which card) gain rewards and cashback for spending money.
