1. Sign up for the website's newsletter if they have one. Many times stores will give you a discount or some type of deal once you sign up for their newsletter. Find out if there is a deal associated with signing up for the newsletter at any store you want to shop at.
2. A reputable online seller must have a history that is recorded with the Better Business Bureau. Check with the BBB before you part with your hard earned money to find out if there have been any major or continual complaints lodged against them. You don't want to be spending your money using a company that fails to offer.
4. If you want to buy books online, you'll get yourself a better deal if you get them used. Depending on the condition you receive them in, you may just end up paying a few cents plus shipping. Make sure you read the description of the book to see if you can find any damages you should be aware of.
5. For those who have questions while shopping, search for a live chat function around the online store. Many big brands (and even some boutique stores) now have this functionality. You are able to chat immediately with a customer support representative to fix any issues or answer any questions before you purchase. That can give you a lot of satisfaction.
