1. Learn the online store's return policy. In case you are considering creating a purchase on an item that you might like to return, make sure to find out if returning the item is an option. Sometimes when you shop online, items can not be returned and you do not want to be stuck with an unwanted item.
2. In case a company includes a newsletter, sign-up. Often, companies will give sneak peeks, promotions and discount codes to people on their own 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 join a company's newsletter should you really like their products and would use a discount code.
3. Read customer testimonials before you buy anything. People are more than pleased to complain about bad service online, so search for sites and testimonials which are terrible so you are aware what you're getting into. You need to take bad reviews using a grain of salt, but if you see many, you know there is a problem.
4. If you are intending to be shopping on the web, make sure that you do it from a computer connection you understand is secure, like one that you have at home. Hackers try to find WI-Fi connections in public places if they are scouting for victims, so avoid shopping when using them.
5. Be suspicious of overdoing it. It is much easier to overspend when you find yourself 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, for example. Give yourself a restriction and stick to it.
