1. If you want to buy books online, you'll get a better deal if you get them used. Based on the condition you receive 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 you can find any damages you should be aware of.
3. If you are going to be doing some shopping online, make sure you understand the liability for every credit card you make use of online. Many credit cards have automatic fraud prevention integrated while others offer it for a minimal fee. You do not want to get stuck with purchases made on your own card in the event the number is stolen.
4. Always remember your finances and credit limits while shopping online. The virtual realm of online shopping has got a lot of people in serious debt. You need to take a look at online shopping in the same way you look at offline shopping. Never buy items online that you don't have the cash to pay for.
5. Turn it into a habit to register for price alerts. It goes even for purchases that you've recently made. Price alerts will let you know whenever a product has dropped to your price you prefer. And if you've recently purchased at full price, you can ask for a price adjustment to meet the new deal.
