Question: is paying for somethin online with a credit card really safe? 

Answer: When you are entering your card information on the internet make sure that the website you are entering it on is secure.  At the top of the page in Interent Explorer is a bar that says address.  It starts out with http.  If the website is secure it will say https.   Also on the bottom right hand side an icon will show up and if you put your mouse over it it will say 128 bit encryption enabled.  Lastly make sure you give your credit card info to a reputable company that you can trust.  Hope that helps.
