1. When you are shopping on the web, you should only shop at reputable stores. If the store does not have a strong reputation, you may be asking for trouble. Many people have had their credit card and private information stolen from shopping on lower than reputable websites. Be careful and protect your private information.
2. Do not forget to comparison shop when you are looking for things online. People usually do this when shopping in physical stores, but they don't think about it on the net. If you choose the first sale you see, there is a chance you are going to miss out on a better deal elsewhere.
3. When you are searching for a spot to buy a product and not one of the results seem to be from familiar retailers, you should be hesitant about entering your data. Look for security signs from Verisign or Cybertrust, so that you know the retailer is not out to take your money.
4. When you are creating any purchases online and you are required to produce a user account, never use the same passwords that you use on other websites. Do not use your e-mail or banking password to make a free account to buy shoes from a web retailer. If somebody was able to see this password, they can have access to not only your profile on the retailer's store.
5. 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 might offer a percentage off or free shipping by simply entering within a simple code which can be easily found by investing a few minutes looking for it.
