1. Make sure that you're entering your payment details on a safe and secure site. Look for "https://" inside the URL of the site that you're seeking to buy something from. If you don't see that or no symbol of any website security, then it's probably a wise idea not to trust those people together with your account information.
2. If you are going to be shopping online, make sure that you do it from a computer connection you understand is secure, like the one that you have at home. Hackers try to find WI-Fi connections in public places when they are scouting for victims, so avoid shopping when using them.
3. If you're considering buying a product online, check out the reviews. The reviews from other people that have used the product can give you a good idea about the product. You could possibly find out the quality of the product, when it worked as described, and if you should create the purchase.
4. Always save copies of your orders and receipts from online purchases. Many stores will redirect you to a page after you've submitted a purchase detailing exactly what was bought, customer information, the prices, etc. You should either print a copy of this or save a duplicate to your computer in case any issues arise before the end of the return period. Ensure that you save any emails about your items' status or correspondence with the company regarding your orders, too.
5. If you are making a purchase online, make certain you use a credit card to pay for the transaction. Charge card users are protected against fraud by federal law and they are only responsible for $50 in these cases. Some card agencies will even go so far as to wave the $50 for you, which means you will not be out of pocket.
