1. 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 should you went to the mall, as an example. Give yourself a limit and follow it.
2. Read customer testimonials before you buy anything. People are delighted to complain about bad service online, so look for sites and testimonials that are terrible so that you know what you're getting into. You need to take bad reviews having a grain of salt, but if you see many, you know you will find a problem.
3. A good online shopping tip to remember would be to leave feedback after buying from a source you've never bought from before. This will help both of you because you'll remember if you've experienced a good experience from them, and they can also acquire a reputation as a seller.
4. Once you enjoy the comfort of frequent online shopping, it's extremely important to keep changing the passwords you use for each and every account. Every few weeks or so, make up a brand new password for your bank as well as the shopping sites directly. Use abstract words, combined with numbers and other odd characters for that strongest passwords.
5. Discover more about the payment methods available from the online store you are interested in. Most stores give you the option to pay with a credit card or with PayPal. A credit card is a safe option as long as the store includes a secure server. If you do not see any details about safety, it is recommended to go through another store.
