1. Read customer testimonials before you buy anything. People are more than happy to complain about bad service online, so try to find sites and testimonials which can be terrible so you know what you're getting into. You should take bad reviews with a grain of salt, but if you see many, you know you will find a problem.
2. When you are shopping online, make sure that you are merely shopping on secure websites. Look in the site URL and it also should display "https" rather than the usual "http" at the beginning. Also have an up-to-date copy of anti-virus running on your computer also. This will ensure that you have a safe online shopping experience.
3. If you feel you will be making a lot of online purchases later on, consider obtaining a separate credit card to use only for these transactions. It is much easier to track all transactions should they be the only items listed with this card's transaction records. Additionally, you don't need to worry concerning your own funds being compromised, even temporarily, if you are a victim of fraud.
4. If you have questions while shopping, search for a live chat function around the online store. Many big brands (and even some boutique stores) now have this functionality. You can chat immediately with a customer service representative to correct any issues or answer any questions before buying. That can give you a lot of reassurance.
5. A great tip to keep in mind when you're thinking about shopping online is to make sure the site is legit. You don't want to be giving your credit card information away to someone who could potentially scam you. Always look at the site to tell if it's professional and safe for use.
