1. Once you enjoy the convenience of frequent online shopping, it's extremely important to keep changing the passwords you use for every account. Every few weeks or so, make up a whole new password for the bank as well as the shopping sites directly. Use abstract words, combined with numbers and other odd characters for the strongest passwords.
2. A great way to stay safe when you shop online is to avoid clicking any web addresses that are sent into your email. If you are expecting an email from a company, go to the actual website and do not click any links. Legitimate businesses do not send emails asking for personal information or account information.
3. Read customer testimonials before you buy anything. People are more than happy to complain about bad service online, so look for sites and testimonials which can be terrible so that you know what you're getting into. You should take bad reviews having a grain of salt, but if you see many, you know there exists a problem.
4. In case you have questions while shopping, search for a live chat function in the online store. Many big brands (and even some boutique stores) now have this functionality. You are able to chat immediately with a customer support representative to fix any issues or answer any questions before buying. That can present you with a lot of peace of mind.
5. Look for the right times to shop online. Often the stores that you frequent will have online sales that follow a time pattern. Many, for instance, schedule sales for the beginning of the month or at the end. If you notice there's a pattern, hold off on buying anything until the upcoming sales period begins.
