1. When you are searching for a location to buy a product and none of the results seem to be from familiar retailers, you ought to be hesitant about entering your information. Look for security signs from Verisign or Cybertrust, which means you know the retailer is not in the market to take your hard earned money.
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 Internet. If you go for the first sale you see, you will find a chance you may miss out on an improved deal someplace else.
3. Be wary of overdoing it. It is much easier to overspend when you are shopping online. You start to rationalize that you can spend more money 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 follow it.
4. 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 whenever a product has dropped to a price you like. And if you've recently purchased at full price, you can ask for a price adjustment to meet the new deal.
5. Before going shopping at any online retailer, do a quick search for promotional codes. Most of the big retailers often have promotions running which are not advertised on their home page. Carrying out a quick search for these codes will allow you to insert the code at checkout to save money.
