1. If you're considering buying a product online, check out the reviews. The reviews off their people that have used the product will be able to give you a good idea about the product. You may be able to find out the caliber of the product, if this worked as described, and if you should have the purchase.
2. Make sure that you're entering your payment details on a good site. Look for "https://" within the URL from the site that you're trying to buy something from. If you don't see that or no indication of any website security, then it's probably a great idea not to trust those people together with your account information.
4. To help protect your credit, use only one credit card for online purchases. This will help you quickly track your spending habits when the bank 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.
5. If you frequently shop online, make certain your antimalware is always top-notch and up to date. Major shopping sites are often targeted by hackers and other shady types who try to steal your individual identification or get into your accounts. Heed any warnings your security software provides you with about sites and report suspicious activity to the webmaster of the shopping site.
