Well. I bought my textbooks today. They cost me $665.61 because I didn't trust any online sellers. And only $665.61 because my mom knows someone who knows someone who has a kid in engineering, i.e. one free decent book. It makes no sense to scrimp on a laptop (which is quite nice, thanks), chair (which is round and comfortable), free pens (which are pretty good for free-quality logoed ballpoints), etc and then to blow $665.61 on five bog quality textbooks and a jumped up professional notebook at full price. Full price using a CREDIT CARD.
