1. Ensure that you're entering your payment details on a 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 indication of any website security, then it's probably a great idea not to trust those people along with your account information.
2. If a company features a newsletter, sign-up. Often, companies will give sneak peeks, special deals and discount 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 join a company's newsletter in the event you really like their products and would use a coupon code.
3. Be cautious which sites you patronize. It is difficult to learn which are around the up or higher and which can be not, but there are a few clues. If the address does not sound right or the design seems off, go to a different site. Additionally, if a lot of pop-up windows begin appearing, close them out and move on.
4. Read customer testimonials before you buy anything. People are more than pleased to complain about bad service online, so try to find sites and testimonials which are terrible so you know what you're getting into. You should take bad reviews using a grain of salt, but if you see many, you know you will find a problem.
5. Always remember your budget and credit limits while shopping online. The virtual realm of online shopping has become a lot of people in serious debt. You need to take a look at online shopping in the same manner you look at offline shopping. Never buy items online that you don't have the cash to pay for.
