1. Many online shopping sites offer discounts if you use a "coupon code". These codes can be found online by entering the words "coupon code" along with the manufacturer or name of the website you will be buying from. They may offer a percentage off or free shipping just by entering in a simple code which can be easily found by investing a few minutes searching for it.
2. Make sure that you're entering your payment details on a secure site. Search for "https://" in the URL from the site that you're attempting to buy something from. If you don't see that or no symbol of any website security, then it's probably a great idea not to trust those people together with your account information.
3. Be suspicious of overdoing it. It is much easier to overspend if 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 in the event you went to the mall, for example. Give yourself a limit and follow it.
4. When shopping online, use a credit card instead of a debit card. This is because bank cards are based on your credit, not the amount of money within your bank account. In case a internet hacker gets your banking information, they can completely ruin you within a point of hours.
5. When shopping online, be sure the site you might be on begins 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. In case a site lacks the "S" in it, you might like to avoid using it.
