@literally45-- I was a victim of credit card information theft. My card information was stolen and used to make online purchases. So I agree with you that this is a very real risk. However, most banks have policies to protect their customers.
When I noticed charges on my account that I didn't recognize, I called my bank and told them about it. They took the charges off immediately and returned my money. I saw more charges a few days later. The bank again returned my money. They cancelled my card and sent me a new one.
So even though this type of fraud occurs frequently, I don't think this should prevent people from making online purchases. Of course, it's important to purchase from large, well known online sellers/sites that are trustworthy and reputable.
