Hi everyone,
Our science lead teacher asked me for help today, and I'm hoping someone in this group has some advice. He needs to order new textbooks for chemistry, physics, and physical science. He would like to know which textbooks are most "popular" these days and how to go about getting them. I have zero experience with textbook purchases, but I told him I'd see what I can find out. 
Thanks in advance for your wisdom!
