I tracked the sell-back prices for two different textbooks over a year.
Again, I used a random online textbook comparison company. Many will work, I’m not sure it really matter, just as long as you don’t sell anything back on campus. Nothing is worse than paying $132 for one textbook and getting back $6 (if you’re lucky) when the semester is over! The site I used is:
http://www.campusbooks.com/
I wrote the date: the highest sell-back price for book #1; then the highest sell-back price for book #2. Mostly I tracked the highest and 2nd highest prices for each book, but I started that a little later. I also noted when Amazon made an appearance because they often trump everyone else’s prices.
The first book is:
Treatment Resource Manual for Speech Language Pathology
- Authors: Froma P. Roth – Colleen K. Worthington
ISBN: 1111319782
The second book is:
Survival Guide for the Beginning Speech-Language Clinician
ISBN10 = 0890799814
For the first book, the highest prices were late October to early November ($96.19) and in August ($90-ish). The lowest buy-back prices were late March ($8.50!) and April when they dipped down into the $20 range.
For the second book, the highest prices were pretty much when Amazon entered the buy-back mix, which was January (as high as $54), August (about $43), and opposite of book one, late March early April ($40-$43). Which shows that it varies by book a little bit. The lowest prices for book one were again opposite of the previous book. The worst time to sell back was in November of 2014 when they dropped to $20-ish and this last June when they were again in the twenty dollar range. The 2015 drop could mean a new edition came out or a better book came out. So it’s good to wait until the book companies are paying more, but not so long that your book becomes obsolete since they’re always writing new ones.
So sell-back prices are more complex then the purchase price, because the school time-lines aren’t driving the process as much. It looks like in general, August is a good time to sell. But you might want to check frequently for the best prices on your particular book or sell to people at your own school.
