1. Make it 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 some price you want. And if you've recently purchased at full price, you are able to ask for a price adjustment to satisfy the new deal.
2. When you shop online, be certain the site you happen to be on starts off with "https". The "S" implies that the site is secure, which entails that you could safely enter your personal information without having to worry about identity theft. If a site lacks the "S" in it, you might like to avoid using it.
3. If you find a great product on your own favorite site, search for it in the search engines before you buy it. Make note of the model number or brand, and do a quick search to make sure you can't obtain it cheaper from somewhere else. You might be able to save a few dollars that way.
4. Be suspicious of overdoing it. It is much easier to overspend when you are shopping online. You start to rationalize that you can spend more for those shoes because you saved money on gas and the food you would have gotten in the event you went to the mall, for example. Give yourself a limit and stay with it.
5. When you shop online, use a credit card instead of a debit card. This is because charge cards are based on your credit, not the amount of money inside your bank account. In case a internet hacker gets your banking information, they can completely ruin you within a matter of hours.
