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 that are terrible so you are aware what you're getting into. You should take bad reviews with a grain of salt, but if you see many, you know there is a problem.
2. If you find a fantastic product on the favorite site, search for it in a search engine before you buy it. Make note of the model number or brand, and do a quick search to ensure that you can't have it cheaper from somewhere else. You might be able to save a few dollars like that.
3. When shopping for a specific item, check several different online stores. Many times with a little searching, you save as much as 25 percent. Look at many different websites to ensure that you are getting the best deal. When figuring each website's price, be sure you include shipping costs in your calculations.
4. To help protect your credit, use only one credit card for online purchases. This will help you quickly track your spending habits when the charge card statement comes in the mail. If you notice any charges that you did not make, call the credit card company immediately and report it to them.
5. Be skeptical of overdoing it. It is much easier to overspend when you are shopping online. You start to rationalize that you can spend more for those shoes because you saved money on gas and the food you would have gotten in the event you went to the mall, for instance. Give yourself a limit and follow it.
