1. Make sure that when you buy something online, you are aware of when the site is secure or not. You may not want your information being compromised in this day and age. Identity theft is quite common, and you also must protect your information whatsoever cost so that you wish to keep making purchases online.
2. To help protect your credit, use only one credit card for online purchases. This will help you quickly track your spending habits when the credit card statement comes in the mail. If you notice any charges that you simply did not make, call the credit card company immediately and report it to them.
3. When you're shopping online you need to be sure that you know who you're buying from. If you're buying on an online auction site, only order from people that have positive feedback. On other sites look to see if they are a reputable company by looking for reviews on them online.
4. In case you have questions while shopping, choose a live chat function on the online store. Many big brands (and even some boutique stores) now have this functionality. You can chat immediately with a customer support representative to correct any issues or answer any questions before you purchase. That can provide you with a lot of reassurance.
5. Be careful in regard to the online stores that you consider buying from. If the web store is poorly designed, filled with misspellings, and overall fishy, you should take your money elsewhere. These are signs that something might not be right about this store. It's preferable to be safe than sorry.
