1. Read customer testimonials before you buy anything. People are more than happy to complain about bad service online, so look for sites and testimonials which can be terrible so that you know what you're getting into. You should take bad reviews having a grain of salt, but if you see many, you know there exists a problem.
2. When you are searching for a spot to buy a product and no results seem to be from familiar retailers, you ought to be hesitant about entering your data. Look for security signs from Verisign or Cybertrust, which means you know the retailer is not out to take your money.
3. When shopping online, most places only accept debit or credit cards. Remember this when you are deciding on a site to look from. If you don't feel at ease providing the company with your charge card information, look for another site. Try to find a website that offers a good page when you're adding your credit card information.
4. Many online shopping sites offer discounts if you use a "discount code". These codes are easily found online by entering the words "coupon code" along with the manufacturer or name of the website you will be buying from. They could offer a percentage off or free shipping just by entering within a simple code which can be easily found by investing a few minutes searching for it.
5. 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 see there's a pattern, hold off on buying anything until the upcoming sales period begins.
