1. Be suspicious of overdoing it. It is much easier to overspend if you are shopping online. You start out 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 instance. Give yourself a limit and stay with it.
2. Ensure that you're entering your payment details on a good site. Look for "https://" inside the URL in the site that you're attempting to buy something from. If you don't see that or no indication of any website security, then it's probably a great idea not to trust those people along with your account information.
3. A reputable online seller needs to have a history that is recorded with the Better Business Bureau. Check with the BBB before you part with your hard earned money to see if there have been any major or continual complaints lodged against them. You don't want to be spending your money using a company that fails to deliver.
4. If you're making an online purchase, don't hesitate to contact customer support if you have an issue. By contacting customer service prior to making your order, you'll learn how helpful customer care is and exactly how quickly they respond. This really is useful information to have in the event that something goes completely wrong after you've made your purchase.
5. Before shopping from a store that is a new comer to you, learn what the store's reputation is similar to. You can usually do a web-based search and discover what others think of the business. It is best to do this so you do not find out the hard way and lose your cash.
