1. Pay close attention for potential sales online starting around Wednesday. Many brick and mortar stores do sales on the weekends, and to compete, many online stores have moved their sales days up by a few days. You can often find exceptional mid-week bargains with just a little online research.
2. Read customer testimonials before you buy anything. People are more than pleased to complain about bad service online, so search for sites and testimonials which can be terrible so that you know what you're getting into. You should take bad reviews with a grain of salt, but if you see many, you know you will find a problem.
3. Always remember your budget and credit limits while shopping online. The virtual realm of online shopping has got a lot of people in serious debt. You need to examine online shopping in a similar manner you look at offline shopping. Never buy items online that you don't have the cash to pay for.
4. When you are searching for a location 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 to take your money.
5. Sign up for your favorite online stores' newsletters. Many times online stores sends out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to save money, you could possibly score some great deals on items you were going to purchase anyway.
