1. Make sure that you're entering your payment details on a good site. Try to find "https://" inside the URL in the site that you're seeking to buy something from. If you don't see that or no sign of any website security, then it's probably a great idea not to trust those people along with your account information.
2. If a website is not secure, do not buy something. Simply look up at the web address when you are shopping. If you notice an "https" as opposed to an "http," you can feel confident enough to insert your bank card information. However, if there is no "s" in the address, move on to a different site to be around the safe side.
3. When a company includes a newsletter, register. 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 sign up for a company's newsletter in the event you really like their products and services and would use a discount code.
4. If you feel that you will be making a lot of online purchases later on, consider trying to get a separate credit card to use only for these transactions. It is easier to track all transactions when they are the only items listed with this card's transaction records. Additionally, you don't need to worry about your own funds being compromised, even temporarily, if you are a victim of fraud.
5. Do more research around the online store you are interested in before ordering a product from their store. If a store does not provide quality service or products, you will most likely find some negative reviews published on other sites. It is best to adhere to online stores having an excellent reputation.
