isaac asimov's science fiction treasury

I went to the bookstore this afternoon to browse the books, which for me usually means going to the science fiction section and checking out the anthologies. I was looking through the books and saw this anthology from Isaac Asimov of some classic SF stories. It was bound in a hard binding, so I thought that it would be expensive, but I picked it up and saw that it was only like $11.99. $11.99! That' almost 800 pages of science fiction stories, new and hardbound, for less than $15.00. Unbelievable. So I bought it.
