Some more ideas.
First of all, although search engines probably wont bring you as much traffic since college kids are not quite as likely to search google for books...
But here are some OVT monthly results
93469 college textbook
21616 used college textbook
17510 cheap college textbook
10436 college apparel
5574 college sport merchandise

Have you hit up the dorms/student housing bulletin boards? The timing is a bit late for this semester but you could try flyers directly to houses/mailboxes in the area a month or two before the next semester begins. This will give people enough time to get books from and most will already know what classes they are taking for next semester. They will also have all of winter break to look it over. What color flyers? Yellow on Black seems to work best at getting people's attention. What is on your flyer? Is it straight to the point or is it a hard read? Can you post your flyer here?
--------------------
Dont give up, once the word starts spreading this is when things will take off.
It may be a long shot, but you could try talking to local businesses and putting coupons on your flyers so people dont just throw them away. Then you will do the job of handing out not only your flyer but business ads, etc...
Sneak some flyers into the library study areas, worst thing that will happen is library workers will throw them away, dont put too many, you dont want to lose too many.
Just some things I would do if I was you
