1. Be sure that you're entering your payment details on a safe and secure site. Try to find "https://" inside the URL from the site that you're trying to buy something from. If you don't see that or no symbol of any website security, then it's probably a good idea not to trust those people with your account information.
2. Make sure to read all the information about any product you are considering purchasing. Just looking at a picture online can be deceiving sometimes. It can make a product look bigger or smaller than it is. Make sure to look at the description which means you know exactly what you are purchasing.
3. When you find yourself making a purchase online, make certain you use a credit card to pay for the transaction. Credit card users are protected against fraud by federal law and are only liable for $50 in these cases. Some card agencies will even go so far concerning wave the $50 for you, which means that you will not be out of pocket.
4. In case a company has a newsletter, sign-up. Often, companies will give sneak peeks, promotions and coupon codes to people on the mailing list. However, be careful. You don't want to sign up for every company's newsletter or you'll soon be buried under endless emails. Only subscribe to a company's newsletter if you really like their products and would use a coupon code.
5. To help protect your credit, use only one credit card for online purchases. This will help you quickly track your spending habits when the charge card statement comes in the mail. If you notice any charges that you did not make, call the credit card company immediately and report it to them.
