I am always on the lookout for places that sell textbooks online. This is because I homeschool the little one. As as result, we have to buy all of the textbooks that she needs for school ourselves. Needless to say, it's not cheap. Brand new textbooks are very expensive so I've been scouring the internet for used textbooks most of the time. Fortunately, there are a lot of places that do that. Textbooks are only used for a year so a lot of times if the user is careful, the books stay in great condition. The ones I bought online are in great shape that I can probably sell them as well once the little one is done with them. Or maybe I can just donate them at goodwill.
