1. If you want to buy books online, you'll get a better deal if you get them used. Dependant upon 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. Get engaged in the social media of the favorite online stores. Brands with big online presences typically put lots of money behind their social media, and this includes offering their followers some mega-discounts and exclusive deals. You generally is one of the lucky ones scoring these works with just a quick follow or fanning.
3. Learn more about the payment methods available from the online store you are interested in. Most stores give you the option to pay with credit cards or with PayPal. Credit cards is a safe option only when the store includes a secure server. If you do not see any information regarding safety, it is advisable to go through a different store.
5. Make it a habit to register for price alerts. This goes even for purchases that you've recently made. Price alerts will tell you when a product has dropped to a price you like. And in case you've recently purchased at full price, you can request a price adjustment to meet the new deal.
