1. Make sure to read all the information about any product you are considering purchasing. Just looking at a picture online can be deceiving sometimes. It will make a product look bigger or smaller than. Make sure to look at the description so that you know exactly what you are actually purchasing.
2. Be skeptical of overdoing it. It is much easier to overspend if 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 should you went to the mall, as an example. Give yourself a restriction and stick to it.
3. Be wary of the emails you get, even if they appear to be from a retailer you trust. Never click on a link that directs you to a site other than the one you shopped on. Should you do, you may become vulnerable to a gimmick. Rather than clicking on an email hyperlink, just go as much as your browser and type in the web site you need to go to. It is much safer that way.
4. When you are shopping on the web, you should only shop at reputable stores. If the store does not have a strong reputation, you may be asking for trouble. Many people have had their credit card and personal information stolen from shopping on less than reputable websites. Be careful and protect your private information.
5. Sign up for the website's newsletter if they have one. Many times stores will give you a discount or some form of deal whenever you sign up for their newsletter. Find out if there is a deal associated with subscribing to the newsletter at any store you would like to shop at.
