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. If you notice there's a pattern, hold off on buying anything until the upcoming sales period begins.
2. Turn it into a habit to register for price alerts. This goes even for purchases that you've recently made. Price alerts will let you know each time a product has dropped to your price you prefer. And if you've recently purchased at full price, you are able to ask for a price adjustment to meet the new deal.
3. When a company includes a newsletter, sign-up. Often, companies will give sneak peeks, special deals and coupon codes to people on the 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 if you really like their goods and would use a discount code.
4. Be suspicious of overdoing it. It is much easier to overspend when you are shopping online. You begin to rationalize that you can spend more money for those shoes because you saved money on gas and the food you would have gotten if you went to the mall, for example. Give yourself a limit and stay with it.
5. When shopping for a product online, take the time to read reviews. Try finding the same product on different sites to read as many reviews as is possible. Reading many reviews will help you get a more general notion of whether or not the product you are interested in meets high standards of quality.
