1. Never give out your Social Security number to an online merchant. This number is not required for placing orders online. Giving an online store your Social Security number can help them use your personal and private information to steal your identity. To prevent that, if you carry on an online store site and find out that as a requirement, do not buy everything from them and shop someplace else.
2. When shopping online, always try to keep in mind the cost of shipping. Many sites offer free shipping on orders over a specific amount. In the event that you have to pay shipping, make sure that it is going to fit into your budget after you've added everything in your cart. Having a full cart only to find out you are unable to afford the shipping is never an enjoyable experience.
3. Make sure that you're entering your payment details on a good site. Try to find "https://" inside the URL from the site that you're attempting to buy something from. If you don't see that or no sign of any website security, then it's probably a good idea not to trust those people with your account information.
4. Always remember your finances and credit limits while shopping online. The virtual realm of online shopping has become a lot of people in serious debt. You need to look at online shopping in a similar manner you look at offline shopping. Never buy items online that you don't have the cash to pay for.
5. Be wary of any emails you get, even if they appear to be from a retailer you trust. Never click on a web link that directs you to a website other than usually the one you shopped on. Should you do, you may become vulnerable to a gimmick. Rather than simply clicking an email hyperlink, just go up to your browser and enter in the web site you would like to go to. It is much safer that way.
