Why Not Sell Collage Textbooks?

Collage textbooks are updated every two years. Not only are collage textbooks more difficult to get but they have a short shelf life. A collage textbook which has value during one year may be absolutely worthless the next year. The collage textbook market is also saturated with sellers. High School and intermediate textbooks on the other hand will provide you with a much wider time window to sell the books at a profit. High School textbooks can still be in popular demand 8 or more years after their original printing.
