1. Look for the right times to shop online. Often the stores that you frequent will have online sales that follow a time pattern. Many, for instance, schedule sales for the beginning of the month or at the end. When you see there's a pattern, hold off on buying anything until the upcoming sales period begins.
2. If you find a great product on your 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 get it cheaper from somewhere else. You might be able to save a few dollars that way.
3. To guard yourself use a credit card while shopping online. The federal government has passed laws to protect consumers in the event of fraud. The amount the buyer is responsible for is really a mere $50.00 as compared to atm cards where the entire balance can be withdrawn by internet hackers.
4. Sign up for the website's newsletter if they have one. Many times stores will give you a price reduction or some type of deal whenever you sign up for their newsletter. Find out if there is a deal associated with registering for the newsletter at any store you want to shop at.
5. Be suspicious of overdoing it. It is much easier to overspend when you find yourself shopping online. You begin 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 limit and stick to it.
