1. If you want to buy books online, you'll get yourself 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 you will find any damages you should be aware of.
2. Always save copies of your orders and receipts from online purchases. Many stores will redirect you to a page after you've submitted a purchase detailing exactly what was bought, customer information, the prices, etc. You should either print a duplicate of this or save a copy to your computer in case any issues arise before the end of the return period. Make sure to save any emails about your items' status or correspondence with the company regarding your orders, too.
3. When shopping online, always try to keep in mind the buying price of shipping. Many sites offer free shipping on orders over a certain amount. In the event that you have to pay shipping, make sure that it is going to fit into your budget after you've added everything in your cart. Possessing a full cart only to find out you are unable to afford the shipping is never an exciting experience.
4. Always remember your budget and credit limits when shopping online. The virtual realm of online shopping has become a lot of people in serious debt. You need to look at online shopping in a similar manner you look at offline shopping. Never buy items online that you don't have the cash to pay for.
5. When you are shopping on the web, make sure that you are merely shopping on secure websites. Look in the site URL and it also should display "https" rather than the usual "http" at the beginning. Usually have an up-to-date copy of anti-virus running on your computer also. This will make certain you have a safe online shopping experience.
