1. Should you be shopping online, never give out your Social Security number. There is absolutely no website that requires this number for you to buy something. If you are being asked for your Social Security number during checkout, perhaps you are on a scam website. Leave this site and discover one which has a better reputation.
2. When you are shopping on the web, make sure that you are just shopping on secure websites. Look in the site URL and it also should display "https" rather than the usual "http" at the beginning. Also have an updated copy of anti-virus running on your computer too. This will ensure that you have a safe online shopping experience.
3. Be mindful which sites you patronize. It is difficult to find out which are on the up or higher and which can be not, but there are a few clues. If the address does not seem sensible or the design seems off, go to a different site. In addition, if a variety of pop-up windows begin appearing, close them out and move on.
5. If you want to buy books online, you'll get a better deal if you get them used. Based on the condition you get them in, you may just end up paying a few cents plus shipping. Make sure you go through the description of the book to see if there are any damages you should be aware of.
